Usernode + Buddylist (Recreate all usernodes)

Hi, I was running my site without usernode module so everybody registered without flaws until we decided to add the My Buddylist to the users profile panel and it showed that the user had no buddies. Ok cool no problem with that, I verified all queries using devel and to my surprise I didnt know that the My Buddylist view needed the usernode module. So that's no problem I installed usernode and it doesnt create a node for each user registered, now thats a bummer cause it means that I have to create a sql script to insert into the node table all the usersnodes per user plus the relationship in the usernodes table!!! Is there a way to get around this? Like a rebuild usernodes table script around?
