Using a repeater region, over a Grid/Vuhdo/Healbot frame.
Vuhdo/Healbot are all-in-one solutions.
Grid requires GridCustomLayouts and Clique to interpret the clicks.
Of the three, most seem to choose Grid, but its an aesthetic choice; all three are equally functional.
The important part is to have an identical sort.
With Grid you can have your team alphabetically in the first column, and the raid/battleground alphabetically in the remaining columns.
With Vuhdo/Healbot, it appears you need the whole raid alphabetically or to designate your team as "tanks" or extra units to track separately.
With an identical sort and the frame in the same place...
The repeater region sends the click from the current window, to only the healer's window.
And the healer interprets the clicks as you have them set.
