Buying Professional Soldiers and Officers? (Fearless Blue)

I just read in the game news that it is now possible to buy professional soldiers and officers for your army, rather than recruiting them from the population. I thought this would be a good idea for my country, because it would free up more workers in the labor force. However, I looked in the Fearless Blue world market, and I could not find an option for buying professional soldiers/officers. Is this feature available yet? If so, how do I go about using it? If not, when will it be available, and how do I use it when it is available? Also, do professional soldiers/officers demand the same wages as civilian recruits, or higher wages, or lower wages?

It appears you can buy using direct market.

GM's have offered them.
