Possible to group inputs?

There are some checkboxes which belong together so I'd like them to appear that way in the CMS visually if that's possible, sort of like a <fieldset>. Not only would it look slightly better, it would also be usefull if I can use one order="#" to move the entire group of checkboxes instead of one order="#" per checkbox.

Right now if got them like this:

    <perch:if exists="progress_25">
        <div class="m-progress-label m-progress-label--one-quarter">
            <perch:blog id="progress_25" type="checkbox" label="Progress 25%" value="25%" divider-before="Progress markers" />
        </div>
    </perch:if>

    <perch:if exists="progress_50">
        <div class="m-progress-label m-progress-label--one-half">
            <perch:blog id="progress_50" type="checkbox" label="Progress 50%" value="50%" />
        </div>
    </perch:if>

    <perch:if exists="progress_75">
        <div class="m-progress-label m-progress-label--three-quarters">
            <perch:blog id="progress_75" type="checkbox" label="Progress 75%" value="75%" />
        </div>
    </perch:if>

    <perch:if exists="progress_100">
        <div class="m-progress-label m-progress-label--finish">
            <perch:blog id="progress_100" type="checkbox" label="Progress 100%" value="end" />
        </div>
    </perch:if>
