There is this widget, which might do something useful here?

cycle-completion-positions
After inserting an unambiguous string into the command line, the new
function based completion system may know about multiple places in
this string where characters are missing or differ from at least one
of the possible matches. It will then place the cursor on the posi‐
tion it considers to be the most interesting one, i.e. the one where
one can disambiguate between as many matches as possible with as lit‐
tle typing as possible. This widget allows the cursor to be easily
moved to the other inter‐ esting spots. It can be invoked repeatedly
to cycle between all posi‐ tions reported by the completion system.
