Pharmacophores from binding poses

Dear all,
I would like to know if it is possible to generate pharmacophores for all poses of different ligand obtained from docking through
"receptor-ligand pharmacophore generation" and then push them for clustering.
Currently we have to select a single ligand in this protocol and not all ligands and it would be difficult if we have to create pharmacophores for say 500 poses manually.
Is there some automation or script available that take one ligand after another and generate pharmacophores.
Thanks in advance,
Regards,
