Official Forms App - multiple image upload

Hi

In the content template we're using with the official Forms App, we have the following code:

<perch:label for="images">
  Attach Images
  <perch:input id="images" type="image" label="Images" />
</perch:label>

This code works fine except when completing the Form we're only able to select a single image to upload. Is there a parameter we can add which will allow selection of several images all at once? This would be a much more elegant solution than repeating the above code multiple times.
