I know one of the things Geoff's working on is fixing various issues around FocusedFX. I'd advise patience for the time being and seeing what Geoff's next build includes. Hopefully it'll be sooner rather than later, but Geoff's recently been through cataract surgery and has a life outside of CSI beyond that, so patience is key.
Now...I still want to offer some help. Have you tried FocusedFXParam? You click an FX Parameter with your mause to make the FX Parameter in focus, and that parameter instantly maps to your fader with no specific fx.zon required. It's one of my favorite CSI features. Maybe you can get by with this in the meantime. Works great for one-fader surfaces. And as long as that mode is enabled, any FX Parameter you click on with your mouse is instantly mapped.
Here are the relevant sections in the .zon. I have Shift+F2 enabling that mode, and Shift+F1 returning back to Home and turning it off.
Code:
