Disable cookies

Is it possible to disable cookies in the current Sitemap Generator v1.2?

I would love to have this possibility, since I am running a shop page with Virtuemart. So I as everyone else suffers from the always appending "vmcchk" in the urls for first visits AND ALWAYS when cookies are disabled.

So when Googlebot indexes my pages, it does so by ALWAYS having "vmcchk" in the link adress, but

when I index my site with for example Sitemap Generator v1.2 (which is pheneomenal btw) it does so by having cookies "enabled" and therefore I don’t get the pages indexed with vmcchk, which ultimately ends with a duplicate page.

I hope anyone can help, thanks for reading.
