Help: Wato Rule Check Parameter

Hi,
could please someone advice me ?
For my plugin i need a wator rule. The Plugins is for flexlm.
So what i need is:
Hostname TCP-IP-Port, List of Services or All
It should look like that
Hostname Port Service
test1 27000 All
test1 27001 service1
service2
test2 27000 service3

Service should be a list, hostname like Checkmk Hostname, Port numeric
All my tries failed.
Regards,
Peter
