Import / Reimport full workflow + Material Orders

Hello,
I often import my meshes and reimport them to find the right size.
I use the quick tweak inside the mesh detail “build” for scale them but in the end i would just reimport them with the scale of 1.
**But the panel to import a mesh , appear just the first time. **
This lead to a mess i want to delete them and import them again, when you already placed the meshes in actors or references, 3/10 times my unreal crash during the operation.

Sometimes the model software have different orientation, even more when you work with multiple people, model arrive to me with different orientaeverytion.
Same thing, the model orientation came out only the first time , it would be simpler “reimport” "reloadd"the mesh with a different rotation.

I find no trace of how make unreal read t**he materials in the right order, **
can we have in the panel the chance of rearrange the material order?
