Importing Vector custom attributes from FBX is not supported in Unity

Hello, is there any particular reason why importing custom attributes of type Vector is not supported in Unity? Docs are stating that you can import custom animated properties: https://docs.unity3d.com/Manual/HOWTO-ImportObjectsFrom3DApps.html

It would be great to support importing of vector as a custom attribute as well as float and integers (which do work). In my rigs I have to split my vectors into 4 floats, which works but takes a lot of extra time just to be able to export a vector. Imagine a rig with 5-10 of these custom attributes, what a nightmare to setup just to be able to import it in Unity.

On closer inspection it seems that Unity does not support Integer types either, i have to use floats for now. If you are not going to add full support at least consider adding a note in the Docs on which types are not supported.
