Choice Node Leading to Next Order

[Jacki3]

Is your feature request related to a problem? Please describe.
When writing dialogue, we use choice orders to extend to another node. However, we may wish to simply call the next Order based on the Choice rather than have to create new Nodes.

Describe the solution you'd like
Choice Orders should allow one to extend to the next Order rather than another Node (or at least choice for both).

Additional context
As duplicating Orders ensures we keep the same portraits and dialogue settings, this feature makes more sense to contain choices within a single Node.
