Locking charitable funds

We have been tidying up Sage and under Projects were able to mark finished items as "COMPLETED - Completed, closed" which will stop any accidental misposts.

I want to do the same with Charitable funds, again to prevent accidental entries being posted and also so we can run reports with only the current active funds.  However, it is not possible in the existing versions of Sage.  Can this be added for new versions?

Thanks!
