Your players can control GM's assets which the GM puts on the Token/Object Layer and assign permission to individual player(s) or "All Players" setting. Wiki docs for this, <a href="https://wiki.roll20.net/Token_Features#Token_Setti" rel="nofollow">https://wiki.roll20.net/Token_Features#Token_Setti</a>... Does this feature help with your game-model placement and playing? I understand it can still be a large amount of work for the GM to set up a whole board game, but once you have the background and pieces on the tabletop and assign control to Players then they can help you arrange the "board". Once you have the board set up, I would recommend making a backup Copy your game, so that you can re-start from the fresh board when you want to play the boardgame again. Others will probably come along to add their tips and experience with this. As a system-agnostic virtual tabletop with cards, dice, chat, tokens, layers, permission settings, I'm sure there are many more methods in Roll20 that can be used to help set up your boardgames.
