add additional class or id to order-pane div's

Since there is no theming function availale to theme the order page on user/%user/order/%uc_order, it would be very helpfull if the oder-pane div's would have an additional div. For example:

<div class="order-pane pos-left">
to
<div class="order-pane pos-left" id="order-pane-ship-to">

or
<div class="order-pane pos-left">
to
<div class="order-pane pos-left" id="order-pane-products">
