Is it possible to limit dropdown results in combo box in application studio

I want to limit the result in drop-list to only “Saleable” and “Non-Saleable”.
How can I do that?
Thanks

you will need to customize the search drop-down list or maybe try doing a quick search and turn off the base search.

If it’s a Reusable Combo, you can add a filter under Filters Append … in this case, I think something like YourColumnName <> 'Non-Saleable Warning' would work
