Is there a way to simply rename a built-in theme?

[longrunningprocess]

My customers don't like some of the built-in theme names, so I would rename them easily in v4 by spreading an existing theme into a newly renamed one in tailwind.config.ts.

In v5, is there some css syntax I can use to do something along the same lines?

renaming abyss to polarnight, for example:

...
@plugin "daisyui/theme" {
  @apply "abyss",
  name: "polarnight";
...
