If I export a book I've already read, I want to add a note marking that

[MarjaE]

In my library, I have a column for each book's status. It can include:

* A device name if I'm exporting it to read or reference,

* Wait, or Extra,

* Incompatible if for some reason it won't be readable, and/or

* Read

I could split Read into its own column, and then open device settings to add that column to the filenames when exporting.

But is there a way to say if #status=":read" then add R, and if #myrating exists, then add the number of stars? So a 4-star book that I've read would get - R4.

And is there a way to update file names for books I've previously exported?
