Add forms from different tables

[ManuOS]

Hi, 
I'm looking for a solution to set up a budget management application.
The scope is to be able to create several versions of budgets, wherein each budget, I want to be able to add several categories and subcategories:
Ex:
Budget V01
(Catering) Catering (supplier (from a selected table), associated sub-categories, etc)
Sub: Coffe Break (price, supplier (from a selected table), etc)
Sub: Lunch (price, (from a selected table) supplier, etc)
(Category) Audiovisuals (supplier (selected), associated sub-categories, etc)
Sub: Sound System (price, (selected) supplier, etc)
Sub: VideoWall (price, (selected) supplier, etc) Audiovisuals:

To be able to change sub-categories for the various versions and compare them later.

Can I create these relationships in Appsheet and have full control over them?

Thanks in advance for your help.

Yes you can do that. All versions just need to be different records with different categories (or same if needed). The approach would be.. first create the original version.. then copy it with a version number etc.
