How to specify data from a list into the value of an thing

I saved the values of the names of objects in the Repeating Group into a list via custom state.

I got a list of Aa Bb Cc Dd.

How can I press the button to pass these values to another object (which will be the source for another repeating Group on another page) consisting of objects A B C D so that each object gets its own entry from this list? That is, so that object A gets record Aa, object B gets record Bb and so on?

I can only load a complete list into each of the 4 objects, but I need each object to get its own entry.
