Yes — pickup points and delivery transporters can offer a time selector with a configurable slot interval. Each slot can cap the total meals or total orders allowed in it; once a slot fills up, choosing it is rejected with "The maximum of «max» meals for this time slot has already been reached. Your current total is «current» meals, exceeding the limit by «over». Please select a different time slot or reduce your order." (or the equivalent orders-based message). Real Time and Catering orders are excluded from this check and use their own, separate time-slot rules — see those Q&As.
