Compound Parent/Reverse Nesting Selector

Dear Generate Team,
Are you planning to implement an extension to the Compound selector, which will allow to use ancestor context?
For example:
Editing .my-selector → + New → SELECTOR (Compound selector: Checked):
.dark-mode &

which should be compiled to:
.dark-mode .my-selector { … }

It would be great if I can decide whether to keep or not* the nesting syntax, for example:

.my-selector {
  color: blue;
  .dark-mode & {
    color: white;
  }
}

* compiled to legacy syntax.
