Donation progress bar for Shopp?

Is there any way to add a donation progress bar in shopp? For example if the organization has a goal of raising 10,000, and is there a way to set up some kind of progress bar or an RSS feed that updates how close they are to reaching their goal?

I know there are other plugins that do this, but the money has to go through Shopp- not paypal or anywhere else.

Thanks in advance!!
