Workfront will not allow a Requestor, unless they have fairly high privileges (we don't want Requestors to see the resulting project, for example), to duplicate their own requests.
We have fairly long intake forms, in some cases dozens of questions. There are also parts of the forms that for a specific requestor are the same answers every time for maybe 1/3 of the questions.
What our requestors have done pre-WF was to use the system we have to duplicate an existing request as a basis of a new request to cut-down on data entry.
I can't really see that harm of even the most locked-down Requestor duplicating their own requests for submissions as a new request.
