Luma vs Saturation curves

The recent updates to Premiere Pro added a series of curves that I find incredibly useful for color grading and they are so intuitive I think they would help a ton for people who do a lot of HSL and Split toning in lightroom.
The Hue Saturation curves, especially the Luma vs Saturation curve is a very quick way to pull colors out of your brightest highlights and darkest shadows. This method of saturation control is fast and super easy and I would love to see these curves in Lightroom.

Yes, we've been begging Adobe for more than a decade to add these curve tools to both Lr and Ps, but they're uninterested in implementing.

Yeah, I realized this after I posted, I'm just so frustrated with it. I've been putting images in a 5K FF RED timeline and desaturating the highlights and shadows in Premiere for certain images I've thrown on Instagram.

well, for now if you'd like to apply a similar correction in Lr/ACR, you can use the range selection tools to desat specific luma ranges.

In case anyone is still wondering, you can do this with a basic curves adjustment. Create a curves adjustment layer and set the blend mode to saturation. On the curve line, click to make 3 dots (one where each line intersects along the curve), so you have 5 dots total including corners (you can use less or more, whatever your preference as long as the midtones don't change). Pull the top right corner down to decrease saturation in the highlights, up on the bottom left to decrease in the shadows. Works like a charm, just not in the same visual manner as Premiere.
