Custom metafields per page

Hi! I recently discovered Locomotive CMS and I'm quit happy with it. But I'm missing the option to define custom fields for all pages. (Every page has the fields, but they are individually per page)

For Example: Every page should have an open graph image and an open graph description. (The authors should be allowed to edit them)

It there a way to define metafields per page? It would be nice to define own tabs, additionally to content, settings and seo. Another solution would be to create own SEO fields.

Thanks in Advance
