This would be possible in LaTeX, but a really general solution would be
difficult. If you want to try writing the LaTeX macros, then my idea
would be to use labels of the form:
pro:theprop
enu:1-pro:theprop
enu:2-pro:theprop
the point being that we can reconstruct the earlier label. I don't think
LaTeX normally knows that you are inside some construct you've already
labeled.
