How to set downtime for application?

I am solving a small problem. I have a lot of servers and services. And Users need to set downtime for application (before deploying a new version, or OS updates).
How can I set it with one click?
I tried to install the icingaweb2-module-businessprocess, but there is no option to set downtime for all hosts/services in the application.

can you help me? I need user-friendly solutions.
Best regards

Hello, you can set a downtime by default in icinga2. Then your module will not sound an alarm. I have attached a small docu of Icinga for you. Maybe this will help you!

I myself use these downtimes also for maintenance and they help a lot!
