Add URL as a dial to a selected group from bar button

When visiting a page, I'd like to to right click on the URL address or on the FVD bar button and get to select in which group I want to create the dial from the visited URL. So, the FVD bar button would have an item "ADD to group..." and when mousing over it would open the groups we have. Actually would work as "Speed Dial 2". It is a very useful and missing feature I'd like to see implemented in FVD.
