Create 'B' team, anybody managed?

If I recall correctly it was announced that teams playing in countries which allow B teams (Spain, Denmark...) would have the option to create one if they didn't have one already. Well, i don't seem able to find the option on the menu if there is one. I've also simulated various seasons in Spain till the end of each year and I've never been notified/offered such a thing. Has anybody been yet able to do this? :confused:
