Best way to create persistent folder mount

[bar_foo]

I have a new unraid setup, my first time using it, and I have a question about the best way to set up a link from one folder to another (I have limited Linux experience). The reason for doing this is that I have a bunch of files that are synced via Resilio, and have everything synced by Resilio into its own user share, but want to have one particular folder accessible within another folder in a different user share, as part of a library from multiple sources. I tried a creating symlink, but it's not visible to my Windows computer via an SMB share. Instead I've used a mount --bind and it works perfectly, but it's not persistent after a reboot. Any advice on how to handle this? 

• Is the best way to make a binding mount and to make it persistent by adding it to the fstab? Does that change have to be made on the Unraid boot USB drive?
• Or is there some other way to reestablish the mount on boot (i.e., a script)?  
• Apparently there are ways to make symlinks work on a SMB share, but they sound a little hacky and less secure. Or is that okay?

I have the same issue, but a different use case.

 

Personally I will probably use a user script on array start; but I'm not sure if this is the best way to do it. It's just what I'm most familiar with.
