Running a group as optimization in design and simulation in off-design mode

Question

I checked nested optimization code in RevHack2020 repository. I want to implement nested optimization for a group. In the subproblem codes, I saw that we can implement run_driver() in compute method for an explicit component (here).

Can I implement run_driver() in group classes? (Since compute() method is for components, could not implement it in a group)

Note: I plan to use nested optimization in a pycyle "element" and it inherits from group class. It is the reason for me to implement in "group" class. Otherwise, I can change my model to explicitComponent.
