@tcarney– Welcome to the Piklist community!
Currently, this is not possible. Here are a few ideas:
1)) Use the Piklist Workflow system. They choose options on one Workflow tab, and then the second Workflow tab displays them using standard PHP conditions.
2) Let the condition show a message that tells the users to save the page, and then display the meta boxes using standard PHP conditions.
Let us know if you need help with either of these.
