Unreal script road block

I am unable to create a script that would import everything from the selected group in the Content Browser of the Unreal Editor. Its not that its impossible to accomplish but there is a lack of documentation on executing commands and scripts while in the Editor vs Game. Even though all of the required scripts are present to make such an addon possible, the lack of information on running class independent of game triggers, post and pre game commands accomplishing this task seemed to go beyond the scope of what I am trying achieve. However, I believe it would be possible to create such a script as I get more familiarised with scripting and the overall limitations of both the technology and the availability of documentation.
