Sadly not. Currently, there isn't any logic that you can apply to the availability of deal stages.
I always recommend that companies find a way to document their CRM SOPs and train their people to follow them. This would be the only workaround I could offer you at the moment.
Is this still the case? We are using an addon that is triggered by deal stage change (via api) so don't want people jumping back a deal stage then forwards again. I've had a look but can't see any way to make people either walk through the deal stage by stage or stop them going back a stage?
Still no change to this as far as I am aware. In your case, you could secure things by adding a mandatory property change as the deal moves between the stages in question, reducing the liklihood of errors. Or you could add additional criteria to the API that prevent it trigging on deal stage only.
