How to run schema:load on the initial capistrano 3 deploy of my rails app

I would like to run db:schema:load in place of db:migrate on the initial deploy of my rails app.

This used to be fairly trivial, as seen in this stack overflow question, but in Capistrano 3, they have deprecated the deploy:cold task. The initial deploy isn't any different than all subsequent deploys.

Any suggestions? Thanks!
