reorienting a mesh from 3d max in unity?

I’ve imported a mesh (3d studio max file) into Unity by drag and drop into the project window.

when I instantiate it in my c# code, it is oriented in the wrong way for my use (unity trasform.forward is not forward for the mesh).

So I put the mesh into a gameobject in the project window and reoriented it so its facing the correct way.
But when I instantiate it in my c# code it still is oriented the original way (and not the way I oriented it in the project/inspector window).
I don’t want to reorient it in my code after instantiate it,

I’d like to reorient it in the inspector so when I instantiate it is facing the correct way (the orientation I want).

How can I do this to the mesh in the project window?

I don’t think it’s possible. Normally, you would rotate the pivot inside Max (in Max, to conform with Unity’s axis system, the green arrow has to point upwards and the blue one to the front).
