Can you add Security onto an existing MCSA?

I currently have A+ Net+ and want to take 270, 290, and 291 to get MCSA before they start retiring test. I am also planning on taking the Security+ after that (because I want it before next year when it expires).
If I get MCSA, and then do Security+, do I get MCSA:Security?
If I get MCSA, and then do Security+, do I get MCSA:Security?
Decide what to be and go be it.

Interesting that they added ISACA and (ISC)2 certs. That's definitely a recent change.
I noticed that a few weeks ago as well.
Ah, the 2 exams. Thanks. Now assuming I have got security+ and the other exam. Then I get the MCSA:Security?
