When uploading a grss snapshot I need to scroll through the page and select the destination manually or raiders get 0 points for the raid.
If i manually select the destination each time it works well...is there a way to avoid having to do that?

You do have to choose the destination. There is currently no way around it, unfortunately. I'm looking into the possibility of making it smarter, but for now, you'll have to choose the destination for each snapshot.
