Do not sync new files/folders in partial folders in Linux Headless

Currently can we disallow Linux Headless to sync new files or folders in partially sync folders?
If yes, how can I enable it?
If not, it would be great to have this function, just like the Windows version.
Thank you.

Right now @Hiroshi_Sasakura, this function is not yet possible. We are working on this feature request.

Thank you.

@Hiroshi_Sasakura: This feature is now available in 1.3.2.
