FR: Specify name formats for uploads on entries

[lukeagsmith]

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

Clients suck at naming things. Duplicate, unrelated, and bad names make the assets folder messy, hard to manage and also don't make for semantic, accessible pages with good SEO.

Describe the solution you'd like

The ability to set a format for the naming of upload files with variables taken from the entry they are uploaded against e.g. {{ slug }}--hero, {{ slug }}--floor-plans etc [file extension maintained].

In some instances where you have more arbitrary assets such as gallery images or a bunch of relevant files to download it would be more useful to automatically add these to a sub folder related to the entry e.g. /downloads/{{ slug }}/ and a new sub-folder would be made.

It would also be useful to be able to carry through the original filename if required.

I guess these would be set in the fieldset YAML

my_asset_field:
  type: assets  
  container: downloads
  folder: '/jobs/{{ slug }}'
  filename: 'Acme-Inc__{{ slug }}-job--{{ filename }}'
  restrict: true
