Honestly the best way to do it is to activate them at a time when you are home every day, even if it's 6am and you log on to activate them then log out to go to work. With maintence today and tomorrow it's the perfect time to set them at whatever time suits you best. Communicate with your officers that are able to set buffs and double check with them on days you can't log in to make sure they get refreshed (discord works well for this).
