(Teammate Forward) / (Teammate Back) Actions in General, Please

As one of the few controller players out there that uses Mixed (Toggle+Hold) Mode, I love how I can toggle L2 or R2 while doing damage and just be able to tap L1/R1 to tab target.

However, while healing, there's no way to target the "next" teammate without untoggling L2/R2, without burning a macro for each possible target. Any chance we could get an Action in the General tab to target the "next" teammate (the way DPad Down does when neither trigger is held/toggled)? I'd be perfectly happy with a console command I could macro as well.
