Hi there,
to be able to make a report on each fields of your form it would be easier to have a look directly at your form than telling you how it should work unless you would be able to handle the JavaScript PseudoCode I'd give you.
Because to make sure the JavaScript will work it is important to know which subforms / rows you are adding instances...
If the image you have provided above with the highlighted subforms are the only ones which are with multiple instances I can give you a snippet code which might work, otherwise I could have a look at your form and do it for you if you'd like.
