Comparebutton changing to Storebutton ?

Hello,

I was wondering, i would like to change the comparebutton to a button that goes directly to the store that provided the products on the comparison theme.
When i put the direct store link in the form “website link” the link won’t work, because the website link is not the one from the lister but it is the same from my website ?
Any Suggestions ?

Best regards,
Dennis
