Create a dynamic filter with powershell?

Hello everyone. I'm rather new to CMS and would really appreciate any help the community can give.

The company I work for would like to distribute software based on department. This must be done with a hierarchical list which I have created in powershell and have confirmed that it does work.

The ps outputs a listing of all employees that fall under a manager. I would like to use this listing as a filter and it must be dynamic. I would like to see the ps run daily and update the filter which would then push software with a policy.

Is this possible? Am I doing this all wrong and there is a better way? Any help would be appreciated.

Thanks in advance!
