Has anyone used CrewAI Flows to create a flow of flows? I have an idea for a master flow that takes in a batch of inputs, uses a router to send different inputs down different sub flows which themselves will contain crews, then the master flow should combine the results from all of the different flows and return one list of input -> output mappings.
I think I know how to do this, but want to make sure there aren't any pitfalls or things I need to be careful of when using a flow in another flow.
Thanks!
