It would be nice if one could trigger a flow from within another flow.

This would give the option to implement the programming concept of "functions" within the flowbuilder.

Our problem is, that our order placed flow is rather complex with a lot of rule checks,
it would be nice to split the trees up into differnt flows, that could be triggered.

Other example, you have a flow "send discount code and tag customer"-flow, which could be used in different flows without the need to rewrite the actions.
