Sortable - sort another list in same order at the same time

Sortable - sort another list in same order at the same time

How can I sort two lists in the same order at the same time?

I have two lists (UL) like this:
<UL id="list1">
<LI>TEXT1</LI>
<LI>TEXT2></LI>
<LI>TEXT3></LI>
<LI>TEXT4></LI>
</UL>
<UL ="list2">
<LI>IMAGE1</LI>
<LI>IMAGE2></LI>
<LI>IMAGE3></LI>
<LI>IMAGE4></LI>
</UL>

I have implemented sortable so I can sort both lists but I want to sort them in the same order. So i want list2 to update when list1 has been sorted, or even better - sort list2 at the exact same time as list1, meaning that when I drag and drop in list1, list2 moves as well.

Can this be done in any way?
