Extend JQL to be able to create a filter for issues in which I or my team had done something (change, comment, ..)

In the activity view, i can see all my past actions (changes, comments, whatever).
It should be possible to get this result as a filter (e.g.: Issues that have been "touched" by me in the last week).

This filter should also be extendable to a group (e.g. Issues that have been "touched" by any user of group X in the last week).
