Change number of row/column when import image-sequence as UDIM

I don't know why it doesn't behave the way it should. When importing mesh from RealityCapure with UDIM (1001) naming convention, on a mesh that has 25udim tiles, it doesn't seem to import properly on blender.

A screenshot worth 1000 words:

Edit : i just found that when reality-capture export the mesh, it rearange number of row-column of UV depending if I choose UVTILE or UDIM. When exporting twice, (because i forgot to set to udim to get one single material) i need to reimport the geometry to get new uv coordinates for each faces.
