Anthropogenic and biogenic VOC in InMAP

Based on variables in the InMAP chemistry input data, it appears that InMAP distinguishes anthropogenic and biogenic VOCs (aVOC vs. bVOC), and gas/particle partitioning of organics is handled separately for anthropogenic and biogenic SOAs (aOrgPartitioning vs. bOrgPartitioning).
According to the InMAP documentation, however, the acceptable species name for VOC emissions is just 'VOC'.
My questions are, then:
1. How can one tell InMAP whether the 'VOC' emissions in an emissions input file are anthropogenic or biogenic?
2. If no such info is given, will InMAP automatically assume anthropogenic VOC emissions and use 'aOrgPartitioning' to produce SOA from the VOC emissions?

I'm including @ctessum @yuzhou-wang @bujinb @pmartien @stephenreid65 @dholstius in the discussion.
