If statements in udev rules

Question

Is it possible to make statements in udev rules via if, else or case?

I imagine something like:

if [ $HOSTNAME == "host1" ]
then
    ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="", SUBSYSTEMS=="usb", MODE="0660", GOTO="local_usb_end"
fi

I did not find anything like that but maybe you can help me with that.
