Show beautytip on specific pages based on PHP code result

First of all Great module, thanks a lot!

I think it would be great if injecting / showing beautytips on specific pages would be configured using PHP (i.e. if particular code returns true or not in specific pages/locations), not only by specifying paths ...

I am talking about the settings page of custom beautytips located at:
my_site/admin/config/user-interface/beautytips/custom-tips/1/edit

Hope this would be considered in future releases ...
