Feature summary (what you would like to be able to do and where):
Starting a check using the check links in Special:SuggestedInvestigations should have a prefill for the check, perhaps something like "user_name from [[Special:SuggestedInvestigations/InvestigationID|Investigation ID N]]" or "user_name from Special:SI" without an identifier.
Benefits (why should this be implemented?):
Papercut having to fill out the reason for a check.
