Routing remove in the M.M. is that how it's supposed to be?

Hallo
For example, i´m using the output of a module multiple times: internally and to an external output jack. Everything is correctly displayed in the “connected to” menu.

However, ican’t find a way to explicitly select and disconnect the external connection while leaving the internal connection untouched. Renaming seems to work.
Did i miss something? There’s nothing about this in the manual.
