Can you make the upstream schedulers into Triggerable schedulers, and have another builder trigger those schedulers synchronously? Then, after the Trigger step, you perform the action that depends on all of the other actions.

I haven't used the set_properties option with Interpolate, but the older copy_properties worked for me.
