how to add dashes to a text GI?

You can use the Concat and Substring to do it by clicking on the pencil on the data field. Example below I am taking 1st 2 characters of InventoryCD and then adding 2 dashes then remainder of the code.

If I remember correctly, InputMask property of the PXDBStringAttribute not only validates provided values, but also allows you to form how it is shown.

Apart from that - you could create a DAC Extension with a custom field:

         PXString]
         PXUIField(DisplayName = "Mondrel")]
        public virtual string UsrMondrel
        {
            get
            {
                return "modified Mondrel value";
            }
        }
        public abstract class usrMondrel : BqlString.Field<usrMondrel> { }

Then use it in your GI.
