Transfer designs and or vinyl groups from Motorsport 3 to Motorsport 4?

I’m wondering if it is possible to transfer my designs or vinyl groups from Forza Motorsport 3 to Motorsport 4.
Can this be done?

The reason I’m asking is because I have taken photos of my custom designs in 3 but I cant upload the photos to the servers so now I am unable to download and share them online, so I’m wondering if it would be worth getting 4 and then downloading my designs there so I could take photos, upload to the storefront and then download them to my pc.
