I am sorry for the delay replying. I believe the Assignment Availability may not be the solution. I don't think what I need is even possible for moodle. For instance, LEts imagine this scenario: Often, my students take training at outside entities, then they upload their completion certificates as an assignment into my website as soon as they have return. For instance, lets say my students may be taking an instructor led CPR training this week, in an outside classroom and they are awarded the certificate of completion today.. but, they can only load the certificate of completion on my moodle website when back tomorrow. The assignment, will mark the submission date as Tomorrow, when technically, they completed training today.
Perhaps a pluggin can do this?
Thank you very much, and I am sorry for the hassles.
