Logical Architecture feature

In my project, I have encountered the scenario where one method or process ( can be depicted as one functional Chain) needs to be repeated until logical condition met (until it is satisfied), how can I represent in Logical Architecture?

It doesn’t seem to be possible as scenario diagrams can be drawn only for functions, exchanges and interfaces but not for capability realizations or functional chains. Perhaps BTree notation implemented by @dsryzhov could help you here.

Thank you for the suggestion.
