Unity Pro 4.x Android Pro add-on

Hello,
I have Unity Pro 4.x license. Is there any way to add Android Pro to that license without upgrading to Unity Pro 5.x? I don’t see such option in store.

From the FAQ:

For how much longer can I buy 4.x add-ons?

Existing Unity Pro customers will still be able to purchase Unity Pro 4.x add-ons if, for example, they want to be able to finish a game without having to pre-order Unity 5.0 or wait until the official release.

Existing customers can also upgrade existing add-ons from Basic to Pro versions in the Unity 4.x cycle.

If you need to purchase Unity 4.x add-ons after March 18, please contact your Unity account executive.
