Hi Kyle - Release and Activity is not supported at the moment. You can refer Docs at Email Rule Engine use cases - BMC Service Desk 9.1 - BMC Documentation for more information.
Additionally for more configuration information on RBE, refer to my friends pulse article at Trending in Support: What’s trending in Remedy ITSM? – Email Engine Rules
Hope this helps!
Thank you for the quick response.
That is unfortunate news. Are you able to confirm whether this would be a difficult customization for me to tackle?
If it is an easier, could you point me in the direction of which forms/active links/filters or menus I should look at first?
