Just wanted to know if its possible to crack multiple WPA2 handshakes in one process.

example:

I am using Pyrit / Reaver to crack a WPA2 cpa file with one handshake in it. It takes about a week to crack 8 character wifi password.

Is it possible, i can add 3/4 handshakes in one files or add multiple handshakes and as it goes through A-Z it cracks them?
