If you have non-standard variable names in your profile file, they can still be used in CFX-Pre. Such names must be typed in as an expression directly in CFX-Pre, because they will not be picked up automatically. For example, your file may contain the variable uvel for velocity in the U direction. On the Boundary Details tab, you could enter <profile>.uvel(x,y,z) (where <profile> is the name of your profile) to pick up your uvel values.
