Notify Incharge of new ticket for their department?

I'm not sure why I am having so much difficulty with this, but after reviewing the documentation I am still unable to find a solution. Apologies in advance if this is an obvious configuration and I am just missing it somewhere!

I am looking to notify a Requestor with the Departmental "incharge" role of all new work orders for their department when the default template is used.

Can anyone help clarify for me? Business rules appear to only allow notification of technicians. Notification rules affect the full scope of all requests and are not limited to department. Custom triggers seem like they might provide an option, but formatting a script to run in order to email a department lead does not seem correct off the cuff...

I am sure I am missing an obvious configuration, role assignment, or design flaw in our organizational setup, I just can't identify what it is. How can I make sure a department secretary is emailed for any new work order created by their department? Thanks in advance!
