Nested blocks (repeatable content inside a block)

Hi there, I need to include custom blocks inside the product description container (which is in this case a bloc inside a section itself).

Basically this is the structure (as you can see in the attached screenshot):

Product (section) > Description (block)

I need to include a slideshow inside the description block but it seems I can’t include blocks (slideshow slides) inside a block (description).

Is this the intended behavior?

Are there any workarounds to include multiple repeatable elements inside a block to create a slideshow?

It would be great to have a blocks system on the right sidebar of the customizer (I am using Online Store 2.0) which which I can create as many blocks I need as slides.

Thanks!
