QBI Enterprise

Hi!  I have two short term rentals.  When I net them together I pretty much have $0 profit.  I have 250 hours for each of them on their own...not that it really matters.  Do I need to combine these as one enterprise?  It seems even if I say both are individual that TurboTax wants me to combine them into one enterprise.  Is there a disadvantage to this in the future?
