Deploy 2 Github repositories to the same Heroku domain

I have:

1. A client GitHub repository (html, JS & CSS files) - contains client directory.
2. BackEnd Github Repository (Node.JS) - contains server directory, package.json, server.js.

Is it possible to setup deployment of those 2 repositories on the same Heroku Domain - So I'll have there the following structure?

• client
• server
• server.js
• package.json
