Combine multiple rows into one row

Hi,

I would like to combine records that I receive in multiple rows into one row.

In short, this is my input:

And this is the what I would like as output:

It's a kind of transpose on the 4 first rows to be repeated. If it were only 2 'columns' per record, I could do that with the multi-row formula, taking the [row-1], but the more columns I add per record, the more complex it becomes.

Many thanks
