Why prevent putting includes under groups?

I am a bit unhappy that I can't include event sheets in a group. In C2, this is possible. I use this to enable/disable whole event sheet at a time to simulate conditional include.

I was posting a bug about this in C3, but found that it was closed "as designed"

https://github.com/Scirra/Construct-3-bugs/issues/655

I could understand if there was just no time to implement this feature, but why would it be omitted by design? Is there a better way to conditionally include an event sheet?

Just use a variable as a Boolean.

You could put all the code in the included event sheet in a group and then toggle that group from the parent sheet.
