How can I disconnect and reconnect a line in Simulink clicking on a special block?

A new block with the following features would help when debugging models:

It would have 1 input, 1 output, 2 states (connected/disconnected) and a parameter specifying what to be put on the output in case of a disconnection (e.g. constant value or ground). It would be nice to have also a graphics on the block, showing connection or not.

The ability to disconnect or reconnect a line using a special block is not available in Simulink.

To work around this issue, please create your own custom block containing a switch-block which allows you to switch the output port to the main input, to ground or to certain constant value.
