Script to add SNMP and Trap setings?

I believe, SNMP config has no TMSH support.

You could easily customise SNMP traps using following article K3727: Configuring custom SNMP traps https://support.f5.com/csp/article/K3727

I was looking more towards adding SNMP Trap destinations with its community strings. I have 5 IP's to add and wanted to make it easier. Is there something that i can run instead of doing it via GUI.

you can probably do something directly in the config files or export and import via tmsh load sys config merge or such.
