Use popup instead of a toast for backend validation messages

Hi,

I often use backend validation in Creatio - I prevent saving a record and throw an exception from an event listener. It works like a charm, but as a result, the end user sees only a toast message, which is small and disappears after a moment, so it's easy to overlook. Is it possible to intercept such an error and display a normal confirmation popup, instead of this one?

It would be great if there is a generic solution, which doesn't require me to change all of my validations.
