Directly render training view #k within Nerfstudio?

[kochsebastian]

Is there a way to iterate through all training view efficiently/select training view #k? The training views are overlaid in the UI, but it is hard to find exactly training view #k which I am interested in?
Or is there a way to start-up/set Nerfstudio directly with the pose from view #k?

Of course I could write a rendering function for the specific view, but I want to test an interactive feature, which would be annoying to render again and again for debug purposes.
