Big app requires one APK and 2 additional OBB files

My game has an APK and 2 OBB files. My question is when I upload my app to applab do I put one of the OBB files under the assets tab and the other under OBB files tab? Also does it matter what their names are? I know the names have to match the project .APK file name but if there are 2 different Obb files is it ok to put 1 and 2 on the file name anywhere? Or will it mess it up? Thanks
