Unreal 5 Morph Targets issue

Hello guys, in older Unreal versions, like 4.15, there was an option to import separate morph targets on the model. I mean, if I already had one morph target assigned to my model and wanted to add another one, I just had to create the new morph target in my modeling software (3ds Max) and then re-export the FBX. After that i re-importing this FBX into Unreal 4.15, and I got the new morph target along with the old one.

Now I’m trying the same process in Unreal Engine 5, but it doesn’t seem to work anymore. If I import a new morph target, all the old morph targets are deleted and only the new one appears. Is there any way to make it work like before? I experimented with the same model in UE 4.15 it worked, but in UE5 it doesn’t. Thank you.
