Actually, you can use "sorry" in ProofGeneral even with
quick-and-dirty mode switched off, if you manually step through the
file(s) containing "sorry".

You only get the "Cheating requires quick_and_dirty mode!" error if an
import statement causes Isabelle to load a theory file containing
"sorry". The workaround is to pre-load any offending files

Of course, if you have a large collection of interconnected theories,
and you use "sorry" in many different files, this might be a pain. But
in that case, you are always free to turn quick-and-dirty mode back
on, at your own risk!
