Simple doubts with scenarios and services

One simple and "basic" doubt 🤪

Imagine I had developed an IDOC-IDOC scenario or File-IDOC, it doesn't matter...

In my Integration Directory all the services and receivers, senders agreements and determinations remain there...

First Doubt:

How can I make them visually disappear without deleting them? Meaning, how can I disable them?

Second Doubt:

At the moment I would like to start another scenario, but that scenario will use one of the business systems created. How can I disable the other the interface determination and the receiver agreement from the other service, so that the older service won't get in execution?

When I activate the new service, he runs the older one instead of the newer...

Any help
