Is there any way Rift bosses could reset every 5 days at server daily reset, similar to Edania bosses?

Right now, my boss timers are so far off from normal playing hours that it’s extremely unfun. Missing them or having them pushed back puts you at a major disadvantage when trying to upgrade alchemy stones.

Thanks for your time please upvote if you agree.

They spawn exactly 5 days from you killing them... So if you want them to spawn at 3pm then kill them at 3pm  :)  

Spawn at 3:00 PM, it takes me until 3:15 PM to get to them, 5 days later it now takes until 3:30, then 3:45 and so on.  After a month you lost 1 1/2 hours, if you are busy at any of the spawn time you lose more time.  Eventually they rotate out of your sleep/work schedule.
