Nested repeater field in CMB2

Hi,
First I would like to give thanks to CMB2 authors for making an awesome plugin.

I am trying to make a nested repeater field using cmb2 plugin. For example, Generally there is already exists an option to add repeater field. What I want is to add repeater field inside of a repeater field. To be more clear, if I add a new entry, I want to add a button to add more entry inside of the parent one.

This is a helpful link what to make. Though it is done through ACF but want same thing using CMB2

How do I do that? Any suggestion is highly appreciated.

Thanks in advance
