Padding a restart

Hello,

I was wondering if it was possible to pad a restart file the same way I can pad my dump files. By example, I have :

dump dmp all custom 800 postLoading/loadingKiln_*.dump id type x y z vx vy vz fx fy fz omegax omegay omegaz radius f_Temp[0]
dump_modify dmp pad 6
restart 1000 restart/loadingKiln*

Is there a way to do something like :

restart_modify pad 6

So that my restart files all have the same number of characters and get in order?

Thank you very much.

Christine
