[support] can i hook a hook?

[Larry Garfield]

Unfortunately in that case it doesn't look like there's a way in.  You'll need 
to either hack the module or submit a patch back to the maintainer to make it 
more flexible.  The latter approach is generally preferred. :-)

Or just decide that having the link there doesn't actually hurt anything so 
it's not worth fussing over.  That's also a viable option far more often than 
people realize.
