Sync only selected bookmark folders between browsers

[PacificCosmophile]

Presently I am using floccus with Dropbox sync in browser A. And there is only one bookmarks.xbel file in my Dropbox.
Folder mapping > Local target >
Bookmarks folder: /Other bookmarks/Misc/Flcs DB 1/
The current structure of my bookmarks is below,

Bookmarks bar
Other bookmarks
  Misc
    Flcs DB 1
      Resource
      Tools
      Vocab
      Recipe
      Music
      Research

Now I want to sync only Resource, Vocab, Music, Research in browser B.
Kindly tell me how can I achieve that?
