New (extra) window for maintained?

[Cokekain]

Is it possible to make a new window that has 5-6 effects, always in the same spot?

So say the first 2 spots are for the cleric's group and single reactive. Basically I want it to always display those reactives in the same spot, show the remaining duration, how many triggers... basically exactly like the current Profit maintained window, except I want to be able to pick and chose which spells go where, and always have them in the same spot.

This would be in adition to (and not affecting) the current maintained window. I want to be able to look somewhere and see that I have this spell, on this person and it has this long/this many triggers left. Would also like to be able to do this with certain procs.

Is there anywhere I could go to learn how to do this? I'm willing to work on it if someone could provide some help?
