Ok, maybe I've missed the plot completely.
With Macroon previously, you'd have your FTbar and your NFbar (Focus Target, and Non-Focus) The customc ondition on the ENTIRE bar then, would mean when a clone cast whatever was on button 1, 2,3 etc would be cast on your Focus' target. This allowed for pure drag and drop of spells from the book on to the bars without custom macros per 5 toons.

I saw in the thread about Macaroon being updated seldom and alot of guys switching to Bartender4, but without much info around their setup. I searched this forums extensively but haven't managed to figure out the same method as yet for Bar4

Thanks
