I've had a good look through their docs, but does anyone know if it is possible to remove the 'days' and 'seconds' options from the popup for the durationbox?

Here is what I have:

```
<label for="time">Duration (mins)</label>
<input name="duration" id="duration" type="date" data-role="datebox" data-options='{"mode": "durationbox", "overrideDurationFormat": "%DM"}'>

```
