Export Mailbox with PSt file size restriction

I wanted to know if there is a option with Exchange 2010 powershell to restrict the export of the mailbox to a paticular size of a .pst file

Example:- If i have a mailbox with 10GB of size, if there a way i can restrict the .pst size to say create 1GB of.pst file which will create 10 pst out of mailbox.

I have checked -ContentFilter option but there is no switch for pst size.

Any help would be appreciated.

Don't Let go..
