Hi Sky,
I am really sorry for the late reply.
I believe this cannot be done in the current system. However, you can tweak the code to achieved this. You can edit these 2 files:
1. .../components/com_easysocial/themes/frosty/profile/default.header.php'
2. .../components/com_easysocial/themes/frosty/profile/default.php
I am really sorry, we unable to assist you with the customization since our hands are tied with the existing development. If this is a priority, please do post them on our sales sections at
https://crm.stackideas.com and our sales department would get back to you with a proper quote.
Regarding your issue on how to add more relationship, currently I believe there is no settings available to do that. However, you can go to this file, and add your relationship there:
.../media/com_easysocial/apps/fields/user/relationship/config/config.json
Hope this can help.
