Is it possible sort the photos on gallery application by the Subject instead of Date ?

I see something at view_gallery_table macro, but I don't know what change at line 50 to do it.

<macro name="gallery_table">
    <table class="gallery">
        <n.page_node.topics_list. sort="pinned-and-root-node-date" start="[n.app_index_record/]" length="[n.app_rows_per_page/]" filter="[n.app_topic_filter/]" >
            <n.handle_empty_gallery/>
            <n.loop.>
                <n.gallery_table_row/>
            </n.loop.>
        </n.page_node.topics_list.>
    </table>
</macro>

It seems to be with sort="pinned-and-root-node-date" or with filter="[n.app_topic_filter/]

No success with the first. If I try change the text  pinned-and-root-node-date with any thing, I have message of:
NAML exception in customized site: 'sort' attribute not set

And with the second I got something,  But shows only one photo with subject="'IC 4651 - Agl. Aberto'", or using subject="'N%'"  I have all photos that subject begins with letter N,  but no sorted by Subject

I caused an error to see the constuction of SQL line and, cleanning the character that cause the error, it shows:

NAML exception in customized site: select * from node where pin is not null and parent_id = ? and is_app is null and (subject like'N%') order by pin

What I think I need is change order by pin to order by subject . Is that ?
