Change Credit Rule end date in ICM

Whenever the participant is terminated we want to end date the Credit Rule Participant Assignment Dates. If the participant has multiple Credit Rules then each and every rule needs to be visited to update the Dates. Therefore, a feature that can update all Credit Rule Assignment End Dates at once is required. This will lead to less dependency on IT team to change the dates.

Note: Participant Assignment > Manage Rollup Credit Rules > Update Rule Hierarchy

Using the above navigation, we can change the credit rule end date but it is impacting the end dated assignment also.

How to stop that? Thanks in advance.
