Ability to change individual item colors in repeated groups, in the same way you can change text. Perhaps with a similar system of dropping a text file of hex values to change them.

Alternatively, the ability to have component states be different within repeated groups would be helpful.

For example, I have a health meter in a table, shows a heart in red, yellow, or green. I can have each as a component state and in a repeated grid, select the individual items I want to change for variation WITHOUT having to ungroup. I'm forced to ungroup all the time, and I do this often.
