By default, the platform does not have this option. You can use the following CSS code.

Please follow the steps below:

    1. Go to Appearances - Customize.

    2. Click on the Additional CSS option.

    3. Append the following:

.bb-icon-folder-stacked:before {
    content: '\ed94';
}

    4. Click Publish.

Screenshot:

The \ed94 part can be changed to any of the options listed in our Font Cheatsheet here: https://www.buddyboss.com/resources/font-cheatsheet/ 

Please note that the code will affect all the icons selected. It will require custom works to create an option to change the icons individually.

Note: Any modifications are considered as custom work already. Know more about our Support policy here: https://www.buddyboss.com/support-policy/
