write_restart command

Hey guys,

I try to get a restart file every N timesteps.
If I add the command (in.liggghts_run)
write_restart ../DEM/post/restart/run*.restart
it writes one .restart file at the beginning.

Is there a possibility to write a restart file every N timesteps ?
E.g. like "write_restart ...... every N" or something like that.

It would help a lot.

Thanks for answering,
best wishes
