How do I add many packages to generate a container in Seqera Containers quickly?

Depends if you know exactly what you want. If you do I think you can just specify the packages in the URL and hit refresh. Alternatively you can use the wave CLI from what I understand, although I have never done this myself. You cannot add a new package to an existing container other than by taking the requirements and adding one and rebuilding a new container.

Thanks Arthur, the URL trick is a good solution for one offs.

I would just use the Wave CLI

Thanks!
