Easy way to activate layouts

we have a ledwall system with a scheduled programming that works well. However, we need to be able to activate layouts with alert messages when certain conditions occur (strong wind, technical problems, etc.). We need to activate them in a very simple way (a simplified web page for example) where the average inexperienced user can activate and deactivate the various alert layouts but not from the xibo interface.
Do you know if there is a way to do it? Is there a way to activate and then deactivate high priority layouts using triggers maybe present in json on the internet or some other way? thanks
