Image Replacement

So...it appears there's no way to replace a single JPEG image. Resolve keeps seeing my replacement image as an image sequence. I can change how Resolve sees sequentially numbered images, but only within Resolve. There's no such setting for the Windows dialog that comes up when using the Replace Selected Clip command.
I can import the new image and change it out for the one in the timeline, but this error should be addressed. I should be able to Replace Selected Clip on a JPEG image in the timeline.
