It seems super counterintuitive that emails coming into my linked inbox, can convert to contacts and I can add deals for, but I can't switch them to leads first...

I'm using Pipedrive to track emails, deals, contacts...sales emails and sequences I haven't sorted out yet, but when someone inwquires about a prodict, I want to turn them into a lead.   That lead may fall through and require following up later on (next month etc) but maybe they convert into a deal...

Right now, it's the other way around.
