Is there a way to enable auditing so multiple factors are considered?

Summary: We want to achieve multiple levels of auditing but through out testing it appears if one rule is triggered out chain of command is stopped.

Example: We want to audit expense reports that are greater than 150.00. However there are some expense types we don't want to approve at all (example personal mileage)

In our setup we audit all reports greater than 150.00

in our Template and Types audit setup we don't include personal mileage as a type to get audited.

Testing we submit a report for personal mileage - 300.00 and report routes to auditing, obviously because of the first rule.
