Ordering rich rules

Is there any way to order rich rules in firewalld on CentOS 7? If I remove all rules and add them back in firewalld seems to put them in whatever order it feels like. Alternatively, can I change the default policy of a firewalld zone? At the moment I don't see any way to have a zone accept traffic by default other than adding a rich rule allowing 0.0.0.0/0; and I don't see a way to ensure that rule is at the bottom. -- Jeff White HPC Systems Engineer Information Technology Services - WSU
