[Data Integration] How to automatically clear combinations across multiple dimensions on import?

Hi everyone,

We have a process where we import a flat text file extract from an external system into Planning via integration. Upon import, we have a Clear Region defined that uses derived values from 2 different dimensions (Client and Geography). Our issue occurs when we want different, but specific intersections cleared for specific members based on the data being imported, so as to not clear existing data.

Below is a situation that occurred recently:

Client 1's data included regions A, B, and C (but data already existed in the application for region D)

Client 2's data included regions B, C, and D (but data already existed in the application for region A)
