Using a NH thermostat for each chunk of slab bins

Dear lammps users,

I have a liquid domain that has been divided into 100 slab bins. Instead of using one general NH thermostat for the whole domain (using fix nvt), I need to use 10 separate NH thermostat for each 10 slab bins. Could you please tell me how to proceed? Is the tchain option in the fix nvt do the same (Say using tchain=10) or I need to divide the domain into 10 sub-domain and apply a thermostat for each sub-domain?

Thank you so much
