Operation dependence in Routes

In SAP, is it possible to have an operation in a route reliant on another operation in a different route completing, before it can start?

Scenario:

Route: Make Pizza

Operation 10: Flatten dough next 20

Operation 20: Put on sauce next 30 (can the start of this operation be made reliant on Make Sauce route being complete or Operation 30 in Make Sauce route being complete?)

Operation 30: Put on cheese next 0

Route: Make Sauce

Operation 10: Mix in Ingredients for Sauce next 20

Operation 20: Simmer in pot for two days next 30

Operation 30: Let cool for two hours next 0

Can this be done without using sub-operations within a single route?
