Vuhdo is an option.

Another is Grid (with GridCustomLayouts).
If you go with Grid, you'll need Clique too (Grid to display, Clique to heal on a click).
Type /Grid Config
Click on Layouts, click on Advanced.
Enter a new Layout.
nameList="ToonA,ToonB,ToonC,ToonD,ToonE"

Not sure if you can do alphabetical with Heal Bot.

Once they are displayed alphabetically, its easy.
The display is the same on every toon.
And no matter who is switched into or out of the group, once the repeater regions have been configured for each combination, it works.
