Hope this is simple.

I’ve got a guitar track that is panned hard on the left, there is no sound on the right. Is it possible to create another track which is the other way round, i.e: guitar panned hard right. I can the balance it out in the final mix?

Unfortunately, not currently. Since tracks can contain stereo or mono now, there is no way to force a mono track, which was the workaround before. I'm working on an idea to allow for this.
