Skin Wrap to Unity

Hello everyone, first time poster here and I wanted to know if someone knew how to do this. I want to export an animation I created from 3Ds max to Unity. The animation is of a cartoon face composed of various meshes (eyeballs, eyelids, eyebrows, mouth,etc.) separated from the head mesh and it has position, rotation and morpher animations. For optimization pourposes I made a copy of all the meshes, merged them into a single mesh and applied a skin wrap to it that uses all the other meshes as reference. The problem is that when I export an FBX with all the animation, deformation and skins options activated it doesn’t take into acount the morpher animation and so, in Unity, only the rotation and position animations are present. If anyone knows how I can do this I would appreciate your help a lot.

PS: I already devised a solution for this, but it is far from eficient and optimal as it adds an hour to an hour and a half to my workflow per animation.

I use an Asset from the store that allows me to wrap one mesh, in my case clothing onto another one and it works with Unity blendshapes and skinned meshes, you can see a quick example of it in the first video and in the second at about 3:55 on wards.

Thank you for the replay. I was kind of looking for a solution inside 3Ds Max. I would prefer to just export a single mesh per animation.
