Windchill purge criteria - by age

I asked this question several months ago, but never received any replies.

I assume that this is not possible?

In Reply to Gerry Champoux:

When defining the purge search criteria, I want to purge only files that are at least 60 days old (modify date).

Is this possible?

I can specify a date range for the modify date, but that would require that I frequently update the end date.
