Produmex Scan - Replace values list with custom query

Hi!

In InventoryCounting i need to select Bin location from the relative button but it shows me only Warehouse without bin location. (See attach.)

Can i show for example a list from a custom query? I need a list of all bin location from OITB table.

I've tried some ways but with no results.

Or can we have the possibility to create a Button that lists a custom query and set the selected value in a custom field?

Thanks and have a happy new year!
