Bookmarklet – force categories

Using the bookmarklet – is there a way I can modify the bookmarket code to force the link-popup to insert one or more pre-checked categories?

something like … +’&cat=126’+ or ‘&category=ecommerce_links’

or similar syntax. I tried playing around but can’t see to find the right field name or right syntax.

Thanks!
