Problems using ServiceProvider and binding handler to queue

[pi3k14]

Hi,
I'm trying to set up Rebus for a new project, a modular monolith, where I configure all subscribers in the same ServiceCollection.

This doesn't seems to be supported?
What I'm struggling with is the registrations of the event handlers, they are registered directly on the service collection and not on the bus configuration. Thereby I can't have different handlers for the same event in different modules.

I see in the examples using the Activator "pattern" the handler is registered together with the bus configuration. Is there some way I can accomplish the same with the ServiceProvider extensions without creating several hosts?
