I have had no success with a problem which forces me to occasionally create
a new identity. I unfortunately created some on the fly and now have
messages scattered throughout identities.

My desire is to combine all past identities into one new one containing all
the past messages and addresses from all the identities.

I do know how to bring one old identity forward using file/import/messages
but believe doing a second would overwrite first.

Hints please.
