Click & Hold on NSButton

I have an NSButton which, when clicked, rotates through several 
related settings for the UI. I have also attached a Contextual Menu 
to the button so that users can Control-Click and quickly go to their 
preferred option without having to rotate through all of them.

What I'd also like to do is activate the CM when the user clicks and 
holds on the button. Is there an elegant way to do this without 
subclassing NSButton?

Thanks!
