Add a "label" field to rerouters of type string. It displays when hovering over a rerouter. Moreover, when holding a modifier key (ctrl?) with the connector tool, select multiple starting or ending connection points until the modifier is released. If selected starting and ending points contain matching labels, automatically connect them if possible. If anything goes wrong (duplicate labels, missing labels, incompatible data types, etc.) a respective error message should be displayed and every connection aborted.
This would reduce a lot of time spent on wire boilerplate, so to speak, and enhance "commenting" / documentation.
