There’s no way to do that – even if you use an ill-advised add-on to pretend it is happening – because your brain can’t act as if your memories haven’t decayed for an extra 15 days.
Those cards aren’t all due today though. They are still due on the 10th, 11th, and every day between then and now – so Set Due Date won’t help you do anything. What you’re really proposing is to go back in time to those days, but you don’t have a time machine, so that isn’t possible.
[The suggestion to suspend all of your overdue cards is also not a good one. I don’t know what the point of that would be other than pretending they don’t exist.]
Your best path forward is acceptance. You have a backlog of overdue cards. You need to put together a catch-up plan and work on getting caught up.
