I see this a lot from the Creator's Club subforum: we'd love to see a feature where we can group decals and copy them from one train to another. Scratch.mit.edu (the website/software that teaches programming through the use of blocks that the user sticks together to make programs) has a feature where you can move a group of blocks from the script into a backpack. This is like your own personal 'global variable' meaning when you close that script and open another one, you can access the backpack and insert the decal into the new script. It would be incredibly useful to have this as a feature for the Livery Designer. We could create a logo or design, group it and easily copy it over to a new train, saving countless minutes! I don't know how feasible this idea is to implement but it's something that would be really useful.
this has been suggested many times, also among other things I have recently suggested for the editor to become more user/creator friendly: https://forums.dovetailgames.com/threads/livery-designer-2-0-features-wishlist.53609/#post-995904
