That's exactly the reason that I suggested prefabs which you could pull apart and customise. That way, people who want to just build coasters can, but then the people who want to go deeper into it and want to really go for detail and accuracy can select the support and adjust it, 1 at a time. That way, everyone's happy.
The target market for this game is the same as RCT3's. No one back then expected it to become a park-building tool for creative minds who wanted to put so much detail and realism into it. Now in light of that, I think Frontier is expecting a similar thing to happen. So as they always seem to go above and beyond expectations, (the in-game supports are already beyond amazing), I wouldn't be surprised if they sneak a feature in similar to what I'm suggesting.
