Schedule pro user

Hello,

Once again I need your help. As we have Mail/Archive problems with a "key" user I was asked if I could personalize the schedule of EV-Archiving for him.

So this is my question : Is it possible to change the run time of the schedule for 1 user or a group of users ?

EV -Exchange Archiving 9.02

Exchange 2010 SP2.

Thank you
