Exporting facial profile/expressions to Unity

I have a character from CC4 which i am exporting on Unity. So everything is fine and i can see its blendshapes.
But i would like to have the expressions from facial profile , for example sad, cry etc in order to use it through blendshapes. Is that possible? I see that some interesting content like this: Cartoon Expressions_Basic50 - iClone/Expression - Reallusion Content Store it says that is not exportable. But it remains the same for the CC4s default expressions?
Even if we can not export it i have a similar qouestion: all these expressions are a combination of blendshapes right? If this is true is there anyway to see this data and transfer it manually to Unity, or other software? When i load an expression on CC4 i can see some weights on face and i transfer them to Unity’s blendshape but i think the result is not the same. Also some motion that the content store provides is it not possible to transfer it (trough iClone maybe) to Unity? Thank you

I learned from another’s question/answer that if you are dealing with facial morphing, you might want to ensure you’ve checked the box for CC4 FBX advanced Export settings called “Convert Skinned Expressions to Morphs”

(however another user indicated that this setting creates New Issues - so if you “fix one thing” it may bring with it other problems)
