Yes, use additional loading (load one and additionally load the other), they will simply add all their levels to the first loaded campaign this way :)

This was actually the reason i started my tool, because the functionality is relativly new.


edit: it wont give you any visual feedback after the additive loading, simply check if it worked by checking the campaign tab.

k i loaded the first level and clicked the level i wanted to add and hit additive load and it said levels added to current camp but didnt c anything in camp tab that lets me know it was added? if u click additive load more than once will it b added more than once? kinda wanted to make sure it worked lol

If you click more then once it keeps on adding afaik.
You can simply delete the levels afterwards ofc

F ME! lol... ofc? is that in the files? if so ill fix that problem tomorrow.
