Mass install SSL certificates in LTM 11.4?

Our current setup uses LTM 10.x and we can just copy .crt and .key files to /config/ssl/ssl.{crt,key} and then create our profiles. This does not work under LTM 11.4.x. So how can we get over 150 certificates in place without doing every single cert and key by hand?

Support is telling me there is nothing out there to do that.
