Require subs to submit a daily log before marking a schedule phase as complete

I assign subs to phases in my project schedule. When they tap "Done" to mark the phase complete, I want to be able to require them to submit a daily log first — otherwise they can close the phase with zero documentation.

Having this as an optional toggle per phase would be ideal. It keeps subs accountable and ensures I have a record of what was done before the phase is officially marked complete.
