[gmx-users] Different Lipids into one Moleculetype (for position restrain)

Hi everybody,

I'm working with a mixed membrane for the first time (POPC+POPE), and I want to restrain the all phosphors  (only Z axis). 
However they belong to different [ moleculetype ] (ie. POPC and POPE), and GROMACS does not restrain more than one molecule type at a time.
What implications would I have should I set both "POPC" and "POPE" to "Lipid", however in different itp files.
Does anyone know a more elegant solution?
