Wrapper for MULTIPLE VALUE FIELD for every n-th "row"

It would be awesome to have the possibility to define "grouping" and a wrapper for each group.

e.g. Surround every n-field values with ...
to output code like e.g.

<div class="row-01">
<div class="item-01">...</div>
<div class="item-02">...</div>
</div>
<div class="row-02">
<div class="item-01">...</div>
<div class="item-02">...</div>
</div>
...
<div class="row-n">
<div class="item-01">...</div>
<div class="item-02">...</div>
</div>
