create a new list which contains all the list members of module 1 and module 2, either manually or by importing action (list-list import) and then create a module with this list and the line items of modules, then import twice from each module and keep those actions in a process
Re: How to aggregate of data with different dimensions across modules.
1. Create a New List .
2. Now Create 2 Line Items in the previous two modules to create the Codes for Importing the List items in the New List. Line Item 1 formula(1st module): CUMULATE(1,FALSE, 'List 1 Name'). Set the Summary of this Line item as 'MAX'.
3. Line Item 2 formula (2nd Module): CUMULATE(1,FALSE, 'List 2 Name')+ 'Line Item 1'[SELECT: Top Level of List 1]
4. Now You can import from both the Modules using these two Line Items as Codes into the new list.
5. Then create a new Module with this list and the corresponding data in the module.
