Asking me to sync regularly

Instead of doing all my sync questions at once, iSync is asking me every 20 minutes for just 20 or 30 or 90. But it seems to ask the same ones multiple times. It's driving me nuts. I've changed syncing to daily but surely it should do a big sync once and then very minor syncs occassionally.

Also, why can't I say always use 'source A' as the lead. Not ask 10 times. I know isync isn't you, but I've never had the issue prior to Soocial.
