Set fixed LOD for all Loaded Tiles

Is it possible to set a fixed LOD for all loaded tiles? I am interested in converting the terrain and buildings to static mesh assets, however this only saves what is currently loaded. For large distances (say 10x10 km), I can disable “Enable Frustrum Culling” and situate the viewport camera above the entire region of interest, but the textures and terrain gradually transition to lower LOD’s away from the camera. What I’d like is a snapshot of the entire region at full quality.
