How can I use summarize to add the sum of a calculated column in a table footer?

Tables\Columns\TextColumn::make('hours_used')
    ->getStateUsing(function (Client $record) {
       return $record->timelogs()
                      ->select(
                            DB::raw('DAY(timelogs.created_at), (CEIL(( SUM(timelogs.total_seconds) /3600) / 0.25) * 0.25) as billable' )
                            )
                            ->whereBetween('timelogs.created_at', [$this->startDate, $this->endDate])
                            ->groupBy(DB::raw('client_id, ticket_id, DAY(timelogs.created_at)'))->get()->sum('billable');
                    })
    ->summarize(Sum::make()->using(fn (Builder $query, Client $record): float => $query->sum(
       $record->timelogs()->select(
                            DB::raw('DAY(timelogs.created_at), (CEIL(( SUM(timelogs.total_seconds) /3600) / 0.25) * 0.25) as billable' )
                        )
                        ->whereBetween('timelogs.created_at', [$this->startDate, $this->endDate])
                        ->groupBy(DB::raw('client_id, ticket_id, DAY(timelogs.created_at)'))->get()->sum('billable')
                    ) )),
