more condition check for gotoif

Hello,
is it possible to check more than one condition for GOTOIF in the dialplan?
Or is the normal way to cascade the diaplan each GOTOIF?

The Background is that I would like to check more than 2 values from a Variable, and then route the call based on the value.

Thanks for your help.
