Additonal request: Longer buffer times for the soon-to-be implemented 5 minute timers

Hi. May I request an additional feature, since you already entertained my previous request at #11925 . Can you add longer buffer times now, lets say 1 minute so that we wouldn't scramble much with the five minute timer request. Thanks. Your work is very much appreciated.

Tagging @xenohedron just in case. Thanks.
