Title: Add preset links to main, combined and distant signals

This adds preset links instead of a notice, which makes it much easier to add zs2, zs3 and other signals to an existing main, distant or combined signal.

Please note that this relies on the names of the signals, so when changing any signal names, the preset name attribute in the preset links also has to be changed.
