Video Add Page

I participate in two different Shutterfly Share Sites, one for my Son's Soccer Team, and the other for Baseball.  I'm owner in the Soccer Site.  I have added Three Videos; one for Baseball and two for Soccer.  I do not wish to add baseball videos on the Soccer site and vise versa.  However, each time I attempt to add a new video  in the Soccer site, Shutterfly automatically begins adding the Baseball Video into the Soccer site.  I have to go back and delete it. Is there a way to remove the videos that are already on the site, fro the ADD window?
