How to retrigger Import dialog

I have meshes with automatic lightmap uvs on second channel. Now i need to make those UVs in 3DS max to improve visual quality.
But after reimporting mesh into editor, UVs won’t update as it still automatically creates Lightmap uvs.
I have to delete static mesh and reexport it again to trigger Import dialog where i can turn off ‘Generate Lightmap UVs’. Bulk Edit via Property Matrix won’t help either.

So, is there a way to retrigger Import Dialog, so i can modify what happens on import? ( EDIT: it without need to delete the mesh and import it again. )
