Hi Elliot
That would require code modification. The file you need to modify is components/com_osmembership/view/profile/tmpl/default_subscriptions.php and components/com_osmembership/view/common/tmpl/subscriptions_history.php
Please note that if you make modification, please move these modified files to template override so that the change won't be lost when you update to future releases of the extension
Regards,
Tuan
