CTS Status Switch for SAP Enterprise Portal

Dear Experts,

In our landscape we use Solman 7.2 SPS14 CHARM functionality to manage transports for SAP Enterprise Portal 750.

We want to restrict users to create transport requests using ChaRM only.

For this we closed status switches in CHARM Administration Cockpit for EP.

However there is still possibility to create transport requests for Portal directly in Transport Organizer WEB UI of communication system (Solman) in respective CTS project.

Here it is possible to create TR for CTS project which status switches are closed.

How do we restrict users to create transport requests for EP using ChaRM only?
