No there isn't. And while Etsy doesn't suggest that you have more than one shop, it's not disallowed. However, if you do make a second shop, be sure to mention both shops you sell on in your profile so everyone can clearly see and there's no misunderstanding.
If you want to move your listings you'll have to do it manually and pay the listing fee again. I would suggest not moving your listings until they expire. I don't know how many listings you want to move, but if it's a lot it could be needlessly expensive. I'd suggest working on the image for your second shop first over a month or so or however long it may take for the listings you want to move to expire, and then start putting your items up. That's really the only way to do it as far as I know.
