Custom tab with Amenities + icons

Hi,

I’ve recently installed GD theme and I’ve realized that from WP admin menu, it’s only possible to exclude certain tabs, and not possible to add a custom tab.

I need to add one tab “Amenities” (property listing), that contains icons with stuff like wifi access etc would show up.
This would also require modifying the new place submission form in a way that enables them to select if there’s wifi, etc… and the elements that are enabled to be displayed on the additional tab.

Is there a way to add this to GD?
