I've been using EVE-NG for the past week or so in order to attempt to create a CCIE Collaboration v2.0 sandbox.
I've been pretty much successful with a couple of little tweaks on the images here & there.
I'm just wondering, is there some way to add a new device template to EVE-NG community edition? I have some devices that i'd like to use additional QEMU custom options.
I managed to add Cisco Meeting Server 2.3 in Eve but using the "cucm-" prefix in the /qemu folder and that worked but it uses the CUCM template's startup custom options.

I would like to be able to create a new Template called "Cisco CMS" and have its own "QEMU custom options" as "-machine type=pc-1.0,accel=kvm -vga std -usbdevice tablet -boot order=cd -cpu host"
Appreciate your input.
