reordering slides imported from keynote/powerpoint

I can't believe I'm the first to request this, so apologies if I've missed it in the forum/requests, but being able to drag and drop slides that have been imported from keynote/powerpoint to reorder them would seem like a pretty basic feature. Am I missing something? This would be really helpful for situations where you've imported the file and want to adjust the order without reopening and editing the original slideshow. Thanks!

And also to hide certain slides for a given cue list.
