Preferred pronouns?

[22408aaron]

I have the G Suite Signature Manager working for our organization and it's working very well, but employees are individually adding preferred pronouns (he/him/his) to their signatures which will get overridden every time we redo our signatures. I looked on this page: https://developers.google.cn/admin-sdk/directory/reference/rest/v1/users?hl=SR and tried several variables, including gender.AddressMeAs, but nothing comes up on the signature. Even if it's populating the preferred pronoun on another field we don't use on G Suite (such as Building ID), any suggestions on how to make this work the best?
