Is it possible to use the workflow to create a ticket (not a child ticket) based on a specific category?  We have a unique business case (less than 5% of workload) where a group is outside of the service desk process and operates independently of the expense workflow we normally use.  

In our BBMR team gets a service request and based on the explicit category D365 Expenses we would like to create a separate ticket for our HR team.  

We do not want to use tasks because of the notifications. If I can turn off task notifications for individuals in a team I would consider it.

We do not want to use Child tickets because we need it to behave completely separate from the original request.
