Unfortunately, I don’t think so. You are correct that the switch to bulb steps are documented, but not the switch to switch. I think what has happened that Inovelli started producing documentation for the Blues AND migrated support articles to a new platform at the same time, and some things are still pending.
Since you’re on Hubitat, @harjms can hopefully help further, although I’m not sure if he’s bound two switches together. Also, I would think that someone here on Hubitat has done that, so hopefully they can weigh in.
Are any/all of your switches in the affected group? This post describes the same issue and the OP wonders if because his/her switches are all in the affected group.
