Inventory Item Access restriction not working in Project Quotes / Cost Budgets

We are running 2023R2.  We setup Inventory Item Access restriction so that certain stock and non-stock items are restricted to certain users (mainly along branch lines).  While the users can only see the items they are allowed on the main Inventory Stock/Non-Stock items GI screen, it appears that they see ALL items when they are trying to pick items in Project Quotes (Estimation tab) or Project Cost Budget (and perhaps in other areas).  Does any one know if this is a known issues or is there something we are not doing right?  Thanks in advance for your help.
