These are those kind of features you can use third party VSTs for. No need to integrate it into a DAW, just because it's a trend right now.
You can purchase Spectralayers by Steinberg for 47,99 € and use it in Studio One with ARA. Spectralayers has one of the most advanced STEM separation tools in the industry. You can also drag and drop individually separated tracks into the playlist window. You can even set the process to be GPU-based, which speeds up the process significantly if you have a reasonably fast graphics card. Much better than the stem separation in FL Studio or Logic imo.
What we need is workflow improvements in the area of drum programming and patterns in general. That's something you can't achieve by using third party VSTs.
