Only customers are displayed on Project Screen Business Account Selector

Hi Experts,

I am working on a couple of things to include all Business Accounts in the selection on Projects (PM301000) screen. As of now only customers are displayed under selector of Business Accounts.

I have tried the standard code as below.

[PXDBInt]
[PXDimensionSelector("BIZACCT", typeof(BAccount.bAccountID), substituteKey: typeof(BAccount.acctCD), DescriptionField = typeof(BAccount.acctName))]
[PXUIField(DisplayName = "Business Account", Visibility = PXUIVisibility.SelectorVisible)]

I have tried below workaround to achieve the same but unable to get the desired outcome on the Projects screen.

 #region Usrbaccount
    [PXDBInt]
    [PXUIField(DisplayName = "Business Account")]
    [PXSelector(typeof(Search<BAccount.acctCD,
    Where<BAccount.type, Equal<ContractExt.HardCodeValues.VE>,
        Or<BAccount.type, Equal<ContractExt.HardCodeValues.CP>,
        Or<BAccount.type, Equal<ContractExt.HardCodeValues.CU>,
        Or<BAccount.type, Equal<ContractExt.HardCodeValues.EP>,
        Or<BAccount.type, Equal<ContractExt.HardCodeValues.OR>,
        Or<BAccount.type, Equal<ContractExt.HardCodeValues.PR>>>>>>>>),
typeof(BAccount.acctName),
DescriptionField = typeof(BAccount.acctName))]
    public virtual int? Usrbaccount { get; set; }
    public abstract class usrbaccount : PX.Data.BQL.BqlInt.Field<usrbaccount> { }
    #endregion

    public static class HardCodeValues
    {
        public class VE : BqlType<IBqlString, string>.Constant<VE>
        {
            public VE() : base(value: "VE")
            {
            }
        }

        public class CP : BqlType<IBqlString, string>.Constant<CP>
        {
            public CP() : base(value: "CP")
            {
            }
        }

        public class CU : BqlType<IBqlString, string>.Constant<CU>
        {
            public CU() : base(value: "CU")
            {
            }
        }

        public class EP : BqlType<IBqlString, string>.Constant<EP>
        {
            public EP() : base(value: "EP")
            {
            }
        }

        public class OR : BqlType<IBqlString, string>.Constant<OR>
        {
            public OR() : base(value: "OR")
            {
            }
        }

        public class PR : BqlType<IBqlString, string>.Constant<PR>
        {
            public PR() : base(value: "PR")
            {
            }
        }
    }

However, when I attempted to run the both logic on the Business Accounts screen, it worked as expected. On the other hand, when I tried it on the Employee Time Cards screen, it only displayed employees in the selector.

I believe this behavior is occurring due to the restrictions imposed on the screens. Am I correct or anyone else have an idea to achieve the same?

Thanks!
