How to add noarch DoD repository?

Hi, I got a RPM repository which has the quite common layout: aarch64/ noarch/ repodata/ src/ x86_64/ I tried to add it as a DoD repository. Then I noticed that: 1. I need to use the same URL for x86_64 and aarch64 repos. Will this cause any problem? 2. There is no "noarch" to select in the architecture list. So how can I get those noarch packages downloaded when need? It seems currently all packages in noarch are not picked thus I have a lot of packages missing dependencies. Thanks, Kai
