Random reviewers based on commit author

I am trying to automate code review based on developers roles.
For example I have one repo with frontend and backend code.
If commit author is frontend developer, then review should assign one of the frontend developer.
If commit author is backend developer, then review should assign one of the backend developer.

"Assign review participants automatically" workflow is perfectly works if review created by developers, but with "Create reviews automatically" it not works, because the user that created review is Upsource (automatic) and all rules from "Assign review participants automatically" workflow doesn't works.

Is there any workaround or feature to vote for?
