We're trying to migrate from HipChat to Slack. For our Service Desk, we had two rules, one which sent a message if ticket was created, and a separate one which sent a message when the assignee was set, but only if the assignee has originally been empty. (ie the first time a ticket was assigned). The way we did this was to use the HipChat integration "Advanced" drop down rule. i.e.
We have two issues:
1) Slack integration appears to only allow you to have one rule per room
2) Slack integration does not have the Advanced option, so there is no way to add the second rule which only triggers when Assignees are initially set.
Any ideas on a work around?
