Filtering for Custom Record Field Aggregations?

Certified Lead Developer

I just started trying to use Record Sync and Relationships and wanted to sum amounts from another table that have a many-to-one relationship with an Id in the main record type.

However, I only want to add rows that are  isActive = 1 or by some other kind of categorization.

Is this doable with a custom expression ? Since the template doesn't have any filtering options.
