Multiple directories in Resilio Sync

Hello!! I love the linuxserver version of Resilio Sync, really simpler to use and install, but have a question:
now I need resilios sync watch various directories, im working with docker on my Synology NAS, and there are folders located on different shared folders.

in the official docker image of Resilio sync is as simple as put this path to any folder you want Resilio communicate: “/mnt/mounted_folders/your-folder”

there is any way linuxserver version can do something similar to the official image?
and btw too, what is the difference between the linuxserver version and the official docker image? because the linuxserver is updated oftenly and the official has 7 months with no updates.

thank you! and sorry for my bad English!
