How to multi texture an object?

Hi, I’m a 3ds max user, I export my files in FBX, some of my objects in a scene have more than one tile so they have more than 1 texture but I haven’t been able to upload more than 1 texture for the object. is there a way to do this?
Here is an image of the upload. I don’t get an option for multiple textures. maybe I’m doing something wrong maybe in the export settings?
