[Plugin: Codepress Admin Columns] Possible to disable sorting for some columns?

Hi, I’ve just started using this plug in and it’s a great time saver – much easier than handcoding a load of PHP.

I’ve purchased the sorting add-on and just have a quick question… is it possible to disable sorting for some columns where it doesn’t make sense (like postcodes, etc.)?
