Hi Gary Turner,
I hope you are well and thank you for contacting us.
You can create two rules and set specific conditions for each rule. If the order meets the conditions of the first rule, the status will be changed based on it. If the order does not meet the conditions of the first rule, it will meet the conditions of the second rule.
If both are not met, there is an Extras option in the plugin settings where the order status can be set to default status.
Please note the attached Screenshots.
I hope this was useful to you, do not hesitate to contact us for any further assistance.
Thanks and best regards.
