It would be nice if we could branch off at a particular action in a table at that state of that action. It is possible to send a particular state of a dataset to a sandbox but not to a derived table. Derived tables always happen at the final state of a table. If we could create a derived table at a particular action in a table, this would be very handy.
Use case: using intermediate results back in a flow without rearranging the subsequent actions into specific derived tables.
