I know you can define a flow of flows in a static sense. I am not aware of anyone who has done this dynamic generation of flows. At least in prefect 1, it would likely require you to generate the new flow, then register it, and the run it. I am not sure all of that would be possible to do in the context of a single flow run but maybe. Would be super cool if you get it figured out, #CL09KTZPX would love to see it
