Openrct2: Allow SHIFT Key to elevate placing track designs

[Superjustinbros]

Currently you can do this with placing station platforms, scenery, shops/stalls, but not track designs.

A very much related thing was raised in #2856, allowing track designs to be placed underground. Since that fits neatly in this feature, the feature requests have been merged.

Here is the original post by @hiandbye7:

So, you probably now this problem. You can save track designs like these two:


But there is no way to place them underground again:

Sorry to bump such an old feature request, but has any progress been made on this?

since RCT does not allow partial underground tracks, putting design underground might be tricky. saving ground level information(setting base ground level?) might useful.

It's also not possible to raise a footpath with shift. If you want to start in the air you have to begin on the ground and build towards the desired height.
