Is your feature request related to a problem? Please describe.

When using Netlify CMS to create new issues, the title of the markdown file created is the title of the post. However, if you have weekly maintenance posts and try to title multiple of them "Weekly Maintenance" or something similar, only the first gets saved.

Describe the solution you'd like

Add a date, this also has the benefit of making posts sort correctly in most systems. Eg. instead of creating weekly-maintenance.md we would create 2018-10-07-weekly-maintenance.md.

Describe alternatives you've considered

I also thought about suggesting things like the components affected or other metadata from the title, but this doesn't make files sort well and may still have the same problem. A date is more likely to make the file unique and easy to find later.
