Invert a Channel into ABC

[cguerramadera]

Dear Dr Humberto, cordial greetings. I have recently been initiating the study of reaction triatomic systems using ABC. I thank you very much for your contributions to improve the ABC code. I would like to ask you about a doubt I have:

If I have a reaction system :

A+BC -> AB +C

How could I invert this reaction channel to study the reverse reaction? :

C + AB --> BC +

Should I make a modification inside the ABC code or maybe I should specify it in the input?

Best Regards.
