Put a board inside a tile
A tile can open a whole board inside your board. In edit mode, tap ⋯ on the tile, then Add destination and Sub-Board. Pick Grid or Canvas for a new board, or Browse Library to use one you already have. Link it to stay in sync with the original, or copy it to make a separate one.
