Yes. the Cabinet feature is nice but what I'm describing is like a "mini-cabinet"; where one doesn't have to load an entire row of modules but rather just a few. As it is, if I put together say four modules to perform a functions then I'd have to create a new cabinet, move those modules to it, save the cabinet, move those modules back to where they were, load that entire cabinet up next time, repeat the process...
It would be much easier to select the four modules and "Save as Container" then be able to load that container patch in future projects.
It's really a workflow enhancement idea.
