Enhancement: read and apply frontmatter kept in json files at directory level

[simoncox]

Is your feature request related to a problem? Please describe.
With 11ty we are able to create a json file at directory level and in that apply frontmatter data to all files in that directory.
FM is not recognising these. For example when I apply the type front matter to a blog post in my blog folder

Describe the solution you'd like
For FM to recognise there is a directory level json file with frontmatter in it and utilise it. Perhaps add that in a way that it is not editable on each post but is used in the Front Matter data (because changing it in a post would cause issues - do you change all of them or just this one - in which case that need to add it to the post front matter and then there woudl be clash - so info and FM front end use only - sorting and filtering etc.)

Describe alternatives you've considered
Duplication of the frontmatter into the .md files which would mean going back through all files and adding it in FM - bit laborious!

Additional context
11ty is very flexible and I appreciate that FM can actually work with it!

Thanks, @simoncox, for suggesting this. I'll take a look at 11ty and its functionality to see how we can add support in FM.
