It sounds like you've tried it only once or twice, and haven't allowed yourself to get used to the process yet? It isn't hard, for anyone.

Don't invert the bike on the workstand. Clamping the downtube means you're probably clamping the shift cables into the paint. Anyway there is no need.

With bike positioned right side up, shift rear derailleur to smallest cog, and flip the quick release lever "open". If the rear wheel falls out, then you're done :-) More likely, it will drop a bit then sit there, you open the rear brake if needed, and pivot the rear derailleur backward, it will drop further, then the cogs sitting on the chain are the only thing holding the wheel up, move the chain and you're done. Putting the wheel back on is the reverse process. For the front wheel, use one hand to hold the fork and one to hold the wheel.

That said, there's no rule that says you can't flip the bike upside down on the floor and remove/replace wheels the way you are used to doing it. Scratches up the seat and bar/hoods, but a bit of carpet or matting takes care of that.
