[SyncEvolution] Multiple google_contacts accounts: how?

Hi My problem: i want to sync two different gmail addressbook on my phone. I just found and installed syncevolution for meego harmattan from OveK repo. I found some info online on how to configure it, and i did, and it work beautifully for one account. For two, i'm not quite sure how to proceed. I tried to set one account as refresh-from-server, and the second as one-way-from-server, but it doesnt really work. The first works fine, but then it seems that one-way-from-server tries to incrementally update the information and thus it doesnt add anything. I dont know how syncml works, but is there the possibility to have a sort of sync option "add from server" instead of only "refresh", that does the refreshing without deleting anything, thus simply brutally adding everything on the server? (then one has to be carefull and wipe everything prior to syncing) Alternatively, is there a way to tell syncevolution to sync only specific google contact groups? in such situation syncing only one account would be enough! thanks in advance best, Paul
