Adding to Landscape


So i am rather new to Unreal engine and i was wondering if i can get some help on here. So i am designing my landscape and i already have an landscape with wonderful vegetation/foliage. I would like to add mountains to my landscape and is that possible after the landscape has been generated? I don’t want to re generate it but rather add it to the current landscape? I know it’s possible in unity with Gaia terrain stamper but Is it possible to do on Unreal? The other way i can think of creating a mountain object but not sure how to get that done or where to find one.
