Force new belts to always be tier 1

It's really frustrating to be wasting expensive construction parts when dragging in new belts between machines. Unless i explicitly select a higher tier belt in the 'transport' menu, belts should always default to the lowest tier available.
It would also be nice to have a 'downgrade' option so we dont have to disassemble and break an otherwise functional build just to recover some precious high tier parts.
Should go without saying, but this needs to apply to pipes too.

Related suggestion, there should be a way to upgrade pipes and conveyors in blueprint mode without having to delete and add new. That way an entire build could be laid out in tier 1 belts and pipes, then upgrading only the specific segments that need higher tier.

I actually find myself in the reverse situation, My own frustration comes from whenever I load up the game on an existing save, I need to go through every type of belt/pipe/machine and manually select the highest tier option to make that option the default for my current session. While utilizing lower level options may be strategically necesarry during some parts of the late-early and early-midgame, I have found myself having far more problems when I made a built and THOUGHT everything was using tier 3 belts when instead it used tier 1, vs the reverse.
