Grouping fields in the edit screen

I have a Pods custom post type with a large number of custom fields. In the edit screen, they all show up in one meta box.

Is there any way to present sets of custom fields as groups of fields? I found a plugin but it appears to focus on front-end display: https://wordpress.org/plugins/custom-field-groups-for-pods/

Are there any suggestions for adding headings for groups of fields in the one meta box or presenting groups of fields in separate edit screen meta boxes?
