Yes you can do it but it’s not a great way to do it as you can’t control how many dots are applied before it moves on to the next target and might take more time than it’s worth.
To do it make a quick dot macro and in the keypress section use just: /targetenemy
this is targetenemy without any conditionals used so you’re not looking to use /targetenemy [noharm][dead] like normal, just /targetenemy on it’s own. It’s effectively tab target
This will keep switching targets automatically every spell or two.
Or you can play with loop limits and pre macro and have /targetenemy used on every X amount of rotations.
