Allow Action to fire another Action

Not sure if this is a question or a suggestion...  probably both.

When you are building an Action, for Action or Else Action, why can't you specify running another Action? You can choose to run an Action Group, but why not just a single Action?

It would be nice to see this added if possible. It just opens up a lot of possibilities to run a list of conditional actions in a way that can't be done through an action group - or currently probably only through scripting which I think deters a lot of users.
