I guess you mean ACTION.

I haven't tried it either, but I'd think that the API accessing the
spreadsheet would have to return the formula rather than the value
computed from it.

And, IIRC, if the additional columns aren't headed with one of
CONDITION, ACTION,... they'd stop access by the spreadsheet parser. So
they would have to be the rightmost columns, which might not be
convenient in general.
