Modify output of wp_dropdown_categories to add term IDs to each option

get_terms ended up bring a more customizable solution which is working for my needs. I was able to easily add the term IDs to each option as needed. Hope this helps someone else.

<div class="location-cats-dropdown">
    <form id="location-category-select" class="location-category-select" method="get">
        <?php $loc_cats = get_terms( array(
            'taxonomy' => 'location_category',
            'hide_empty' => true,
            'orderby' => 'menu_order',
            'order' => 'ASC',
        ) );
        if ( $loc_cats ) : ?>
            <select name="location_category" id="location_category" class="postform">
                <option value="0">Byway Categories</option>
                <?php foreach( $loc_cats as $loc_cat ) : ?>
                    <option value="<?php echo $loc_cat->slug; ?>" id="term-id-<?php echo $loc_cat->term_id; ?>"><?php echo $loc_cat->name; ?></option>
                <?php endforeach; ?>
            </select>
        <?php endif;
        wp_reset_postdata(); ?>
        <input type="submit" name="submit" value="Filter" />
    </form>
</div><!--location-cats-dropdown-->
