How to duplicate, split a grid loop and keep the cards from the second part of the loop Cards 5-8

Hi team

I have a grid of 8 loops, I need to split it into 2 sections.

If I duplicate the tag into another tag and remove the loop to 4 in the first tag, I get the first 4.

How can I preserve the 4 cards in the second row without configuring it all again?

If in the second duplicate tag I change the loop into 4 the second row will disappear and I will need to configure all the cards from the beginning.

How can I do that?
