VBSeo only for new Content

hi,
We already have couple of vbseo licensces in place however we want to try vbseo on one another forum where we require only new showthread urls to be vbseo enabled.
Keeping all the old urls intact (native vbulletin type)

is this possible ?

Thanks.

This is not supported in current vBSEO version, all URLs (both new and old) are rewritten.
