Mounting works with run and service create, but not faas-cli up. Is that a feature or a bug?

This has been discussed before, but above title tells me this may be a bug not feature.

I don't want all my hosts to have all the models, but to keep them in centralized place only once.

Have a FAAS on Docker Swarm, and want to mount a Gluster based folder to container. I can do it with commands run and service but not when I deploy through faas-cli up using yml file. Is there anything within faas code that disables these mounts?
