Any decent way to automate Offerings? BAMA

I'm Running BAMA this league, I've been trying to drop the amount of buttons needed, I've been able to drop curse/mark via my merc, but right now the last small annoyance is Offering. While curse/mark doesn't need to always be up while mapping the merc tends to do find with popping it on map bosses, not the case with Offering as its pretty strong and could do with being up most of the time. Any decent ideas to automate it?

So far I've tried CWDT, but the uptime is pretty rough since incoming damage isn't consistent. I've tried Arcanist Brand which has been better overall but still feels quite clunky when mapping having to recast it constantly, I'm thinking about trying the trigger when focus craft on helm, could also keep it linked to the brand so that it automates the brand that automates the offering.

Any other decent things to try?
