Is there a way to import GPG key revocation certificate to BitBucket git server?

[Antti Seppälä]

We would like to use GPG signing for git commits. I tried the signing out and I got the basic process working. Now I'm able to sign my commits. I also evaluated key revocation process. I can do it in my own machine and the end result is a key revocation certificate. Is there any way to import it to BitBucket server or use an external key server with it?
