fix not taking dynamic group

Hello Lammps Admin,

I am trying to use a dynamic group for fix temp/rescale, but I am getting a error message that this fix doesnot allow the use of a dynamic group.
I am using the development version as of 14 Jun 2014.

I need to drain the energy of the system by rescaling the velocity of atoms at the boundary. The atoms in the boundary thus need to be updated every few timesteps.
I donot see that making fix temp/rescale take dynamic group causes a problem.

Thank you.
LAMMPS is a great resource.

No fix is enabled for dynamic groups until
someone looks at the code and changes it (if necesssary)
to work with dynamic groups. No one has
done that for fix temp/rescale.
