Add FX List Can I filter out the mono FX?

[mister happy]

Hi,
I would like to clean up my Add FX list so it's easier to make selections. I already have a folder for some of the most often used FX. I am wondering if there is a way to hide all the mono versions of the FX all at once, or if I need to manually select all the stereo versions and collect copies of their listings in another folder.

Is it possible? Maybe with a boolean type entry in the filter dialog?

Thank you!
