Is there a way to disable motion detection for multiple cameras at the same time for a certain period of time that is not regular?

In our case we have installed three E1 outdoor cameras to monitor a building. Currently, of course, they sound the alarm at any movement, which is of course correct and important because the club building is not inhabited and weapons are stored there. In the building there are of course some regular events (3 to 4 per week), but the building is used irregularly for various events (birthday, wedding, etc.). For these events we can not and do not want to reprogram the schedule every time. It would be better that when the first alarm comes and we thus get to know that the event begins we can confirm the alarm for a certain number of hours according to the motto "All good" and the phones thus no longer ring.

This setting should also apply to all clients that have access to these three cameras.
