Default Still Image Duration

BIGGEST problem with this seems to be that it is only applied to still images imported into the project AFTER you've made this change to the duration. If you imported an image into the project, without placing it on the timeline, and then change the duration before you put it on the timeline... it won't affect that image. I changed my duration to 1 frame, and the images I imported before that change still go on the timeline at 5 seconds/still. It's a very stupid way of handling it when you're working on multiple machines and importing tens of thousands of images. It's very frustrating. We should be able to change the duration, and drag any still at any time onto the timeline and have it adjust the still to that duration.
