I don’t believe so as very specific criteria has to be set each time a purge is ran (at least in Live). Purging also has separate stages e.g. you have to purge ledger & diary before an actual policy/client record can be removed.
For all I know there may be an overnight command for Prospect to purge quotes/prospects ‘marked for deletion’, however we review these first as anyone can press Esc K (and maybe doing so for the wrong reasons).
Bottom Line, I feel nervous purging when doing manually, I would not like the idea of records disappearing from the system each night etc.
Sorry, I’ve not been much help!
