Is it possible to break the strict top-bottom flow order in "activity (beta)" diagrams? I mean, besides doing splits or looping. I'm thinking it might be nice to "restart" further up sometimes in order to get a more compact diagram. I'd typically want this when the flow moves to a different swimlane, which might for instance mean placing "Continue" directly to the right of "Activity" in the below diagram. Is there a way to achieve this? If not, consider this as a feature request...
UML code:
@startuml
|System 1|
start
:Activity;
:Over to...;
|System 2|
:Continue;
:Back;
|System 1|
stop
