Expense policy adminstration on Domestic and International travel meals expense type

Description (Required): We are exploring ways to enhance the expense policy associated with an expense type by making it more comprehensive and layered. In the current setup up the policy is not quite working as intended or in line with our policy.
Our current Policy states that a person's meal should not be over $AUD80 per transaction. We have set up the policy to capture attendee information. If someone spends $100 for 2 people, we would like the person to manage attendees and be able to split it $50 pp, which means no policy violation. This is working in the current setup up but what is not working now is that if a person is by themselves and they spend say $40, then the expense transaction is making them manage the attendees, enter themselves, and then enter the $40 again;
