Need Help Merging Scenes?!

Hello UE4 Community,

I am currently working on a game which I have made a post about I am just waiting for it to be approved… Not sure what the hold up is with that. Right now we have multiple scenes (maps) and I am trying to merge them all together. One of the members on our team said the following
“copy the content from the alley pack over to the pool project (exactly same folder structure)
then open Ued once with the map you like to copy from
open another Ued with the target map
select all you like from the source map and past in target map.”

I am wondering if there was a easier way to put these 4 different maps into one or if I would really have to add the pack to the project and then copy and paste everything by hand…

Thank you,
