dump 1 all custom 5 dump.coordNVT id type x y z
If you use this instead:
dump 1 all custom 5 dump.coordNVT.* id type x y z
you can get one dump file per snapshot.
If that’s too many, then do something like:
dump 1 all custom 5 dump.coordNVT.1 id type x y z
run 100000
undump 1
dump 1 all custom 5 dump.coordNVT.2 id type x y z
run 100000
undump 1
dump 1 all custom 5 dump.coordNVT.3 id type x y z
run 100000
undump 1
etc
