Hostname variable concatenation

Hello!
I've used Nagios for around a year. Took over the one running in the office, and I've learned a lot since then.
On to brass tacks: I need to monitor the bandwidth on multiple network devices (switches, routers, load balancers), so I read some of the documentation and setup mrtg to handle the data acquisition.
I've been told that we need to monitor the special interfaces (PortChannel, VLAN). The way the Nagios documentation recommends I do it is by defining one check per IP per interface, hardcoded:
This is not useful to me, as I'd have to generate over 100 service definitions per network device.
Is there a way to concatenate the hostname in the command?
So that check_command would end up like this:
