Is it possible to customize since()?

Carbon::setLocale('el');
  //...
  Tables\Columns\TextColumn::make('credits.expiration_date')
                    ->sortable()
                    ->since()
                    ->placeholder('Δοκιμαστική περίοδος')
                    ->tooltip(function ($record){
                        //return $record->credits->expiration_date as human readable, in greek language. don't include time, only date
                        return Carbon::parse($record->credits->expiration_date)->isoFormat('LL');

                    })
                    ->label('Ημερομηνία Λήξης'),
