Ghost underground belts on ghost space platforms

[Serinat]

Current issues:
1. When trying to place underground ghosts on still unconstructed space platform tiles, said ghost doesn't indicate the undergorund part and both sides will face inwards
2. Underground belts do not work if they have holes in-between (intended feature, but you have to manually place tiles between ends)

It would be nice if
a) underground belts placement worked exactly as on surface;
b) placing an undergroudn on space platform auto-filled tiles between ends

If you find it hard to understand, please notify me and I'll try to explain it more!

Additionally, undergrounds and pipes don't show the measurement markers, so you don't know if they are too long to connect without guessing
