sky replacement feature

I would love to have more advanced settings in the sky replacement function in Photoshop, like selecting the part where you want to replace your sky at, often the tool doesn`t recognize the sky and it would be great if you could help selecting it or better said define what the sky is. Another feature for this tool I wish that you could redirect the perspectives of the sky to give it even more a realistic feel to it. Closing the gaps to the edges and also have a kind of a dehaze function. 
This would save a lot of time and you would have more control when it comes to sky swaps. At the moment I still use Color Select tool and masks to do my sky replacements because the sky replacement feature has to many limits yet to achive the most realistic feel. I think it would not be a huge effort to make this happen. Please make it happen!
