And, as with any good question, the answer is: "It depends". It's pretty straightforward to reverse a reaction by creating a new one and copying the reactants/products from your example in as products/reactants in the new reaction. This will work as long as you don't use query features in the specification of the reaction. Unfortunately it stops working sensibly pretty quickly once you introduce query features. Here's a gist showing some of this. https://gist.github.com/greglandrum/5ca4eebbe78f4d6d9b8cb03f401ad9cd I'm having a hard time coming up with even a hack solution that isn't a ton of work, but I'll think about it a bit more. There may be a way to make this work on the C++ side. To help with this, can you give a specific example of the kind of reaction you'd like to reverse?
