Not on 8.1.4 which is the latest and greatest.

I saw a patch that implemented it about a year ago but I don't know the
status of it.

Isn't the SessionId unique and only inserted once? So:

INSERT INTO SessionLog ( ... SessionId ...) Value ( ... 'XXX' ... )
SELECT id FROM SessionLog WHERE SessionId='XXX'

BTW, I do find your audit schema a bit odd in that sessionid in sessionlog
is not used throughout the other tables, but instead you seem to refer to
it indirectly by the id of sessionlog. (Having sessionid meaning different
things in different tables is also a tad confusing.)
