Custom notification - Pass/access all placeholders in script at once

Hi,

Is there a way to access the placeholders values from a custom notification script?

Background: If I understand correctly, you must pass each placeholder you want to use in your custom notification script as a parameter separately. This can cause the parameter line to be really long and confusing/hard to read.

It would be great if there is a way to pass all the placeholders data using one variable and parse the content within the script. Or even better: All the placeholders could be set as environment variables within the process so the script could access them directly. Maybe there is a way to achieve this already, but I don't know about it. So any help appreciated.
