Religion change in BNW

Hi again,
I noticed something changed in religion, in BNW expansion.
Is it not possible any longer to choose two "spreading enhancers" (I honestly dunno how to call them) like it was possible in GaK?
Like, I used to choose Itinerant Preachers + Religious Tetxs (I know, rather easy win) to have my religion spread like wildfire, and all by itself, with no use of missionaries...
Now in BNW we are allowed, it seems, to only choose 1 of these...the slot of the second one is now used for general improvements (like Tithe, Pilgrimage, Just War...).

Am I wrong?
Has it anything to do with the introduction of the last social policy of the Piety branch?

Moreover, how does a religion obtain "reformation beliefs"? Is it only possible for a certain religion?

Thanks!
