if... a feature to let you choose inputs to match the inputs in the corresponding transaction
was... implemented here on the main chain, any future forkers would be forking software that had the tool
I think this is the only solution. I can't code it. And if the devs don't have time, then I wish someone, a coder from the Monero community, would work on it.
Me, I would certainly donate to an FFS. How does one initiate such a project?
