Restart paused campaign for a few contacts?

Your software
My Mautic version is: v3.3.2

Your problem
My problem is: 1-2 months ago I made a huge mistake while warming up my new IP (via a campaign, 6k subscribers received an email instead of 200).

I immediately paused the campaign but would like to restart it now - however of course, if I would restart it, again 6k subscribers would get an email .

How can I restart a paused campaign just for a few subscribers? (so I can slowly increase the number of emails sent)

(Btw, the campaign has 40 emails (2-3 days apart), and the subscribers are at different events of the campaign (so somebody got so far the first 3 emails, somebody 10, 20, or whatever).)

Could somebody please help me how I could solve this?
