If you are working in native EnergyPlus (i.e. using IDF Editor), it's a simple matter of setting the 'Surface Name or Radiant Surface Group Name' for each system to the correct internal source construction surface.
If you're using OpenStudio, however (which you seem to be, based on the mention of 'CeilingsAndFloors'), it's somewhat trickier. I've documented an issue with forward translation for this object whereby none of the 'Radiant Surface Type' inputs will translate to EnergyPlus input with only ceiling surfaces listed in the Radiant Surface Group Name.
What you should be able to do is have one system with Radiant Surface Type = "Ceilings" which would translate to an object that references the internal source construction ceiling surfaces, and one with Radiant Surface Type = "Floors" that does the same for floors (as you describe). The fact that you still get the error that a surface is referenced by more than one system indicates to me that my issue is still valid (e.g. the "Ceilings" setting actually translates to ceilings and floors). Until this gets fixed, I think you're limited to editing the idf (see here) or writing an EnergyPlus measure.
