Adding additional funds to fundraiser

I am using the fundraiser plugin and I want to be able to add funds to the “total” that did not actually come through the widget. We are a fund drive that has other ways to donate, and I would like to manually ad those numbers to the widget so people can see the total amount raised… not just the amount from the widget. I tried editing the meta data in the database, but that just blanks out the entry. thank you.
