Craig,

Nope. You are limited to using VBA, either through a UDF or a macro.

Is there any simple or creative formula (not macro or user defined
function) that I can use to determine if a given cell reference (e.g.,
cell C133) is part of a merged range?

Maybe use some kind of function that won't work on cells that are part
of a merged range could give me a known error that I could use as my
indicator?
