Send-back remark should be only visible for the radiologist to whom the report has been sent back

Then the other radiologist needs to reach out to the chief radiologist who sent back the report to the report creator who is not available and ask for his change proposals? Maybe the remark of send-back should also be readable by RIS admins, too?

What about if report creator is not accessible and report should be finalized by another radiologist? If remark of send-back cannot be read the report can't be corrected as requested.
