Allow requestors to duplicate past requests

[#1]

Requestors have asked for a way to duplicate a past request so that they don't have to fill in all fields again for a similar type of request.

[#2]

This would be very helpful because we have a lot of custom fields that need to be re-entered for every request.

[#3]

We need this, too.

[#4]

There is a way to do it already. It's just not super easy. We have a process and are currently developing another way that seems to work slightly better. However, I do think overall this could be improved within the system.
