vRA 7.4 OVA Blueprint Network Questions

I'm attempting to create and deploy the vRO 7.4 appliance as a vRA blueprint.

Question 1: Are we able to leverage vRA network profiles to populate the OVA network settings?

Question 2: When manually specifiying the network properties in the blueprint, they are not being set at deployment time. Is there something specific we need to do here? I noticed the network properties are the only ones not being set (ie hostname and root password are being set).

Also, if there's better documentation than what's available here. Please let me know.
