Check if meta key exists

Is there a way to have the Conditional extension evaluate if a meta key exists in the postmeta for a page/post? So something like:

Don’t process this trigger if…
Merge tag = {postmeta {page_ID} meta_key}
Operator = Is equal to
Value = <blank>

So the above would only send a notification if the meta_key existed/had a value for the page with that ID. Not sure how to accomplish checking for an empty value or if a meta key exists for the conditionals extension. I don’t see an option to set the operator to greater than or less than or I could use “greater than” and then zero.
