When importing obj files, the vertex indices order is changed. Is there any way to solve it?

Question

This is part of my obj file. The goal is to create indices in the order of the vertices.

The coordinates of the index of the 0th vertex of the blender do not match the 0th vertex of the obj file

It was confirmed that the vertex of the first line in the obj file is assigned an index of 523 in the blender. Is there a way to generate the indices in the order of the vertices of the obj file? Or is there a way to specify the vertex indices in the obj file format?

The solution with Blender 2.9 is quite easy :

Import your .obj, that is File -> Import -> Wavefront (.obj)
In the Blender file View, click on the file you want to import
Open the Geometry panel, click on Keep Vert Order;
click Import OBJ

Now the vertices ID should match the .obj indices.

When importing obj files, the vertex indices order is changed. Is there any way to solve it?
