SEPM - merging exclusion policy

Hi Everyone

I have a question about merging exclusion policy.

Here is the scenario.

You have Group A on top.

Then below this, you have subgroup B.

On Group A, you create a new exclusion policy called A-Exclusion. In this you exclude C:\test.txt.

I then need to create a new exclusion on Group B.

What is the best way to create a new Exclusion policy, whilst merging what was set in Group A.

I can think of few ways, but what is generally the best way?

1. Break the inheritence on Group B, and edit the local exclusion policy. This way, i am adding to what is already excluded from the group higer up the tree. However, i dont like doing this locally to the group, as it can be hard to manage.

2. Break inheritence on Group B. Copy the A-Exclusion policy, and paste as a new policy. Rename it B-Exclusion. This will retain what was set in group A. Edit B-exclusion to add further exclusions. Then assign this to Group B. Hence, B-exclusion policy will now takeover in Group B.

Is there other ways? Like how it works with GPO's in AD?

Thanks,

DM.
