I am surprised that no one ask about it before, but search returned no useful result.
I start tinkering with Universal Device Poller (UDP), I added a template and then realized that it would be better to remove some parameters fist as they wasn't replaced with those from template.
...and here is my question or two:
1) how can I "undo" adding template -- is there a way to remove it from UDP?
2) how can I remove chosen poller from UDP, as for example here: remove two earlier created by me to replace them with those provided by template?
