Running SDP 13008

We have employee termination requests coming in via email, and I'd like to execute a script upon a defined Description that applies a Service Template to the request (change from the default request incident template and apply a service catalog template instead)

This way the long task list attached to the Service Template is automatically applied without our service techs having to edit the ticket and apply the template themselves

not really seeing that this is possible with the functions provided in documentation, the only workaround i am seeing is to apply task items individually as an array in JS?

thanks!
