[gatsby-source-wordpress] Trigger incremental build when new users are added

[Haldaug]

We run an online newspaper using wordpress as the CDN. We use the wordpress users to store info about our authors and co-authors. Whenever we want to publish an article with a new co-author, a cold build of the site is necessary for the new user to be added to the schema. Is it possible to trigger an incremental build when a new user is added?
