How to overwrite bookmarks on Safari with iCloud bookmarks?

[JuryDuty]

I use Safari on my iPad and I've decided to start using it on my MBPro with the Yosemite update. But when I go to turn on bookmarks in iCloud on the MBPro, it says it wants to MERGE them. I don't want that. I just want it to overwrite my local bookmarks with the iCloud bookmarks (the ones from my iPad).

Is there a simple way to do that? I'm sure I'm missing something...
