Sunfire in Macro

I’ve been looking at building a Feral (Balanced Specialization) Ranged macro that would include the Sunfire spell for those times you cant get close enough to use feral abilities. Sunfire wont fire from a macro using /cast Sunfire as feral unless you add (Solar) to it, i.e. /cast Sunfire(Solar), but GSE strips the (Solar) when it is saved, reverting back to /cast Sunfire. Any ideas for fixing?
