Schedule Snapshots in Parallels 7

Is there a way to schedule, when snapshots should be taken?
I'd like to take snapshots in the middle of the night, so I don't get bothered during my daytime work.

If it's not in the product, could you please consider this as a feature request for Parallels 8?
Thanks

 

you can now adjust only the frequency - every 24 hours, every week etc. I will forward this request as a FR
