Question about the R/C druid spells .ini setting

I still don't have the 1.3 patch for BG2 yet on OS X (btw what's up with that @Beamdog??), so I can't play around with this setting.

Does anyone know if it can be toggled via Weidu? I.e. is it just configurable, or actually moddable? Could I just do a

COPY_EXISTING ~baldur.ini~ ~~
   REPLACE_TEXTUALLY ...

...to toggle the setting? It would be nice if I could give players a way to control this with a Weidu mod rather than having to edit an .ini file. (Wouldn't a .2da have worked better for this kind of thing?)

Anyone know if Weidu can do this? Thx
