chunk/atom and ave/chunk

Dear lammps users,

Is there a way to append output to files when using fix ave/chunk in a restarted simulation?
The documentation says fix ave/chunk needs to be respecified in restarting input scripts but if I do so and keep the same output files (which I would like to do) I replace the old data with the new ones, which is not the point. I want to prolong a simulation which ended too early. So is there a way those files could be open in 'append' mode or anything like this?

Thanks.

if the documentation doesn't say so, then you cannot, at least not
without modifying the source and recompiling.
in general, i can only recommend against appending files from HPC
applications like LAMMPS. the risk of generating corrupted files is
far higher than the benefit of the convenience it offers. files can be
easily given unique names through simple use of variables (especially
now with file style variables) and then they can be easily combined
after the fact.
