Is your feature request related to a problem? Please describe.
I would like to group items for some organization, but I don't want to make it feel like we're sending the user through tons of different prompts.

Describe the solution you'd like
Something like what's pictured below. This example is split into two prompts which each display multiple groups.

Describe alternatives you've considered
Today, as far as I'm aware, we'd need to split each of these groups into a separate prompt. It would make the user go through seven prompts in the example above, which just feels too long.

Additional context
I'd like to use this for svelte-add, which can be run with npx svelte-add and is available at https://github.com/svelte-add/svelte-add
