We need to be able to delete and/or inactivate multiple

We need to be able to delete and/or inactivate multiple constituents at once.

I am working on cleaning up our database and one of the things I am doing is marking constituents inactive and/or deleting them if they fall into specific categories I have made. For example, anyone who hasn't given in the last 10 years will be marked inactive. But, what I am finding is that it tends to be a lot of constituents (we are talking tens of thousands!). If I were to mark each one inactive, one at a time, that would take me months if not years to do since I can't spend 10 hours a day/7 days a week doing it.

To make this easier, it would be great if there was a way to make a query and tell Altru to mark everyone in the query selection Inactive (and/or delete). Thanks!
