I've played around a little with this but never found a way to do it that I thought worked for the Atlantic puzzle.
Here's a very bad example I just made of one way you might use emoji to make inter-clue references:

too confusing/unsatisfying right now -- but I made the builder partly so that people would experiment...I bet someone will figure out something good!
Yeah I can’t say the emoji linkage do it for me. Perhaps, though, what about color highlights? Sven’s Sudoku Pad lets you apply colors to cells and this is used to great effect during solves on cracking the cryptic. Flipping that from solving to authoring, if you wouldn’t mind adding the option to allow highlighting of clues from some simple preset color list, that might be able to give people some options.
