When setting up an SLA, I want to stop the clock when an internal comment is created.

[Arturo Olvera]

Stopping an SLA for Initial response does not show the option for internal comments. Is there q way to add SLA conditions?

Unfortunately there currently is not a built in way to do it or a way to do it through JQL.  (https://jira.atlassian.com/browse/JSDSERVER-4286)  I was not able to find a feature request for this.  You could always add a transition that stops the SLA and your agents would enter an internal comment on the transition screen.  I know this is not as slick but it is a work around.
