Unable to export debian repository for air gapped deployment

Problem:
I cannot figure out how to export debian based repositories from Foreman/Katello. When I attempt to use the hammer export command (either repository or content-view) I am told that it is for yum files only. How do I export debian based repositories? I cannot find any documentation on this.
Expected outcome:

Foreman and Proxy versions:
foreman 1.22 Katello 3.12
Foreman and Proxy plugin versions:
foreman 1.22 katello 3.12
Other relevant data:
[e.g. logs from Foreman and/or the Proxy, modified templates, commands issued, etc]
(for logs, surround with three back-ticks to get proper formatting, e.g.)
