Relative flux is simply the flux of the target star divided by the total of the flux of the comp stars. If you want normalized relative flux, enable a "Norm/Mag Ref" mode in the Y-data panel (with "Out Mag" disabled). Normalize relative flux is then a fractional flux change (i.e. a change of 0.01 is 1%). If you want relative magnitude change, then enable a "Norm/Mag Ref" mode and also "Out Mag" in the y-data panel. Then the units changes are in magnitude. Units of mmag can be output by also adjusting "Y x 1E" on the Multi-plot Y-data panel from 0 to +3.
