I am not convinced the best way to do something like that is on an entity event. I think it should be more direct flow of information. It would be really cool if you can share kind of what you are trying to solve for your users. LIke business flows etc.
I mean without all these automation Events we can use, SambaPOS wouldnt be what it is today 
Whether its something worth assigning resources too and implement is up to you, but I think it would be very useful in many Entity management scenarios without using or being the Ticket (screens).
