Hi @billdjango,
Unfortunately, this improvement is outside the scope of our theme as it is related with Author Avatars List. Our theme and plugin only show Customizer controls to help build the needed shortcode for your page. However, the parameters handled by the shortcode are defined by Author Avatars List.
So, it’s best if you try to reach the plugin authors as they will be more informed and better suited to take charge of your request.
To go further, we invite you to post your request on their support forums:
https://wordpress.org/support/plugin/author-avatars/
We remain available for all support requests related with the use of your theme.
Best,
