XF 2.2 Where can I change the "edited by" time treshold?

I thought there could be set up some time where a user could edit his posts before the "editted by" appeared.

For example, I want users to be able to edit their posts for let's say 15 minutes, to be able to fix typo's. However, I don't want the "editted by" shown for the first 3 minutes.
Is there a way to configure it like this in Xenforo? I thought there was but I can't find it anymore.
