Gam feature plugin question

Hi Guys

I am needing to create a system where we have many many different levels.

From a artist / user point of view I would like for each level to be a game feature plugin so the main project doesn’t get bogged down with every other level. Also so a user only needs to have on disk the levels they are wanting.

Is it possible to create a game feature plugin that contains the main .umap that will be loaded? So that when unreal is started it only loads a shell with no .umap. It then has a drop down list box to choose game feature plugin where the .umap is located.

Thanks

Ben
