Tunnels for FOR loops are autoindexing by default. Sometimes this is not the correct option for very obvious reasons and we get a broken wire.
The diagram editor should be smart enough to try the "other" option (e.g. no autoidexing) if a broken wire results. If the other option succeeds without a broken wire, it should be used automatically. Maybe the tunnel could "glow" for a few seconds with a small option box (similar to e.g. when pasting into word: keep formatting, text only, etc) that would disappear after a while where we can click and overwrite the automatic handling.
The image shows two wires that would be a candidates for autocorrection of the indexing option. In both cases, LabVIEW should disable indexing automatically to avoid broken wires.
If both options result in a broken wire, nothing should happen, as before.
(Similarly for while loops. e.g. if I wire a scalar across the boundary to an array indicator, it should autoindex.)
