[Validation plugin] Is it possible to validate a field using two existing methods?

[Validation plugin] Is it possible to validate a field using two existing methods?

Hi,

      I've tried to look for an answer for this but none available so far...

      I am trying to validate a field that could be either an email address or an url. Both email and url validation methods exist already so I am hoping that I don't have to create another function...

      Is it possible to do so in the current framework?

      Thanks
