capturing in ${VAR//(*(\/)(+([^\/]))?(\/)/_${BASH_REMATCH[1]}_}

When you are doing a var expansion using the
replacement format ${VAR//./.}, is there some way to
put parens around some part of the expression and reference
them as in the [[V~re]] RE-matches?

Couldn't find anything in the manpage, but I could easily
have missed something...?
