Sub "Network Maps"? | TheDude 4.0beta3

Hi,
I want to clean up the “Network Maps” tab in the “Contents” table on the left side of the application.

Is it not possible to create a hierarchy in “Network Maps”?

For example:
You are in a Network Map called “USA.” Under this, you create a submap called “New York,” and within that, you have “New York site 1” and “New York site 2.”

Currently, all of these are at the same level in the “Network Maps” hierarchy, which makes the “Network Maps” list very long and difficult to navigate.

It seems that it is similar to the latest Dude v7.
