Yes, it works. But it is senseless, because pfx - import usually means that you want to import private key also. Otherwise you can convert pfx to any other format and import it by wine control gui, and it is not a problem. In this scenario private key is not imported. So, private key importing is the problem now.
The private key should be included. Why do you conclude that it's not imported? Please provide steps to reproduce.
