Is it possible to add a component built in Plasmic Studio to a custom section like "Section example"?

I’m working with Plasmic and have a question about organizing custom components in the Studio’s side panel.

I know that I can use PLASMIC.registerComponent to register React components and place them in a custom section like Section example", for example:

PLASMIC.registerComponent(PlasmicAsymmetricCarousel, {
  name: "PlasmicAsymmetricCarousel",
  section: "Section example",
  props: { /* ... */ }
});

However, what I’d like to do is add a component that I created visually in Plasmic Studio (not a custom React component), and have it show up under a custom section like "CMS Custom Components" in the insert panel — without having to wrap it in React code manually.

Is there a way to achieve this directly from within the Studio?

Currently we only allow grouping of custom Plasmic components in the Project panel at the top and in the Components panel - you can name your component “CMS Custom Components / PlasmicAsymmetricCarousel” to have your preferred hierarchy:

Is it possible to add a thumbnail to a custom component?

It’s currently only possible for code components via the code component meta.
