Which is the Send Handler (Host) that my Dynamic Send Ports use?

When we define a Static Send Port, we can set the Send Handler that this Send Port will use:

But when we define a Dynamic Send Port, we haven't this possibility:

Then, which is the Send Handler for this Send Port? After debugging some pipeline components, I found that the process that I have to attach is the default Send Handler for the protocol that the Dynamic Send Port uses:

This is a problem when we have two Dynamic Send Ports, that have to execute under different host instance processes, under the same protocol.
