Use NCM config change template to remove non-standard syslog servers

Hi, I'm trying to write a config change script that will:

1. configure 2x syslog destinations on IOS devices:

.e.g. "logging server 1.1.1.1

          logging server 2.2.2.2"

2. Remove any other defined syslog servers (e.g. if "logging 3.3.3.3" was already in config then remove - "no logging 3.3.3.3")

Lastly the logging destinations will be the same on all devices so I would rather not have to input variables each time the script is used.

Any help gratefully appreciated!!
