how to organize multifield component dialog?

so i have a multifield in my component dialog and inside it is another multifield. As you can imagine, it can get quite tall/big.

I'm wondering what options are possible so can I can better organize my dialog so it's not overwhelming my authors.

I was thinking perhaps something like an accordion? (or in my case, I was thinking of using a checkbox to collapse and expand)

Thanks in advance for the response.
