Google managed wildcard ssl in multiple projects

[Ftornik]

Hi.

I have a web app deployed in 3 environments (dev, stage, and prod). Each environment has its own Google Project.

I want to assign the following subdomains to each environment:

• https://dev.myapp.com
• https://stage.myapp.com
• https://prod.myapp.com

Google Certificate Manager provides me with a wildcard SSL for the root domain. But I could use it only in one project because CNAME for domain verification is not unique. 

Is it possible to have the wildcard certificate for my root domain in all three projects?
