Update interval (in minutes) per list

Hi,

thank you for pi-hole, this is a awesome project!

I testing some lists at the moment, some has a update frequency of one week some of 20 minutes.
At the moment I can only update all lists with pihole -g this result in high load on the servers with the once a week updated lists.

Is it possible to add a interval (minutes) per list when the next update should run?
Here was a topic but no solution:

Thank you.

there isnt a per-list update interval in pi-hole right now. gravity rebuild is all-or-nothing, so pihole -g hits every subscribed list.

workaround that usually works when one list updates every few minutes: dont point gravity at that remote url directly. cron a small script that curls the hot list into a local file (like /var/lib/pihole/hotlist.txt), add that file path as the adlist, and keep normal gravity on a slower schedule for everything else. then only your cron hammers the fast list. the weekly ones stay quiet.

still a fair feature request for real per-list timers. that path just avoids beating the slow providers every 20 min.
