[FEATURE REQUEST] Allow variables in file location

[malevans]

My use case is that I often have additional notes I would like to keep in subfolders under the main book folder. Currently I create the book note but then i have to manually move that to a folder I have created. Any additional notes related to the book are moved to a subfolder.

It would be very useful to be able to dynamically build the book folder by using the {{title}} variable in the 'New file location' option like

3. Resources/Sources/Books/{{title}}

So that a folder is created using the Book Title as the folder name.

I've seen similar functionality in other plug-ins that is extremely useful.

Hopefully you might be able to add this to the development list.

Cheers
