Repeater Field - Item Title

Need Help
#1

Hi! I have a repeater field configured as follows:

'type'    => 'repeater',
'displayMode' => 'builder',
'useTabs'     => true,
'itemsExpanded' => false,
'titleFrom' => 'system_name',
'groups'  => '$/abc/test/models/sections/sections.yaml',

If the “system_name” field is empty, the label “Untitled” is displayed.

If the specified field is empty, can the group name be displayed instead of ‘Untitled’?
