Swappable bookmarks toolbar sets

I have extensive bookmark collections organized under my bookmarks toolbar. I use different bookmark sets at home and work. I need them remain separate but would like them to be backed up and synced. For example, if I'm at home, I want to be able to toggle over to my WORK bookmarks with all the latest updates. Basically, I need distinct bookmark identities but don't care about keeping other work/home stuff isolated. I tried making home and work profiles, but syncing them to my Mozilla account merged the bookmarks which was a mess that took a long time to straighten out. Can 2 profiles be synced to the same Mozilla account without merging bookmarks toolbars? If I have to create a separate Mozilla account for each profile, that kind of defeats the purpose. I've looked at the available docs but can't see a fix. Can someone advise how I can either: A) Sync multiple profiles (with bookmarks) to my Mozilla account without merging the bookmarks toolbars B) Find another solution to let me toggle bookmark sets.
