3rd party app to place static meshes

I have a bunch of static meshes. There are times when i’m away from my computer but want to make various parts of my scene. My phone and laptop are usually with me. The laptop is old.

Are there any 3rd party software that will allow me to place static meshes in 3rd space?

Edit: i would like to place static meshes and export the scene to UE as a single static mesh
