Form adding L3 Cost Type # list item only to specific C3 Cost Centre # list item
I currently have a module dimensioned by 2 Numbered lists:
* C3 Cost Centre #
* L3 Cost Type #
I want to present a module on the UX dimensioned by these two lists and a line item for the Amount. The thing is, I want to be able to add more L3 Cost Type # list items from a Form, and that should only be added to a specific Cost Centre. I suppose I need some sort of Filtering module to help out? I know one way could be that the user manually marks booleans to TRUE in a filtering module based on the above 2 lists which you then filter on the UX, but then it becomes very manual.
