How to import FBX into 3ds max so that all original animations are transferred?

Question

3D

Friends something I can not understand.
Situation. I have a FBX file with walking animations in all directions. Those. they are all in one file. When importing into 3ds Max, in the settings I am only prompted to select 1 animation from all. And if I then try to add this file through Merge and in the settings with Update Animation, then it simply overwrites the first animation.
Actually the question is how to import all the animations at once, or at least how to connect them sequentially?
