The patch in #27713 might work for this (I haven't tried it). I don't
believe there is any other way/trick.

For nesting screen sessions, I think a better solution is to just use
different escape keys. Are there other use-cases where such notification
can be useful? (as I have stated before, I am trying to avoid adding
kludge to hardstatus/caption unless there's a compelling enough reason
to do so).
