Short USB to Dock Connector?

I have a USB extension cable which i use to put a USB port out front of my iMac where I can easily connect it to a variety of peripherals used occasionally: external HD (archive), DSLR, iPods etc. When I want to connect my iPod however, I also have to pull out a USB-Dock connector cable. It’s always getting knotted in a drawer (seemingly by itself) so what I’d like to have is a connector with no or very short cable. Is there such a thing available?
