Age of Empires 2DE requirement for mod/data set friendly setup

I for one whom love creating and using dataset mods such as IA + UI, this is an essential requirement that I need.

Ingame Menu changes.

A section in the main menu that allows you to load/select a Data set for the game to use and that will take immediate effect. That will eliminate the need to enter the “Standard game” section, choose a data set, enter the match and then exiting, just to have the data set loaded.

I need this for playing data set saved games, to create senarios / campaigns using a data set, extensive testing of mods and so on.
