Custom fields in templates#968

It would be nice if templates allow for adding custom fields to include notes like

• Ball size
• Buildout Line
• Heading permitted
• Punting / Drop kicks permitted
• Number of substitutes / # substitution windows / When subs allowed
• etc.
  Instead of keeping a separate document to refresh what is allowed in each league / it would be great if this could all be populated either in a Format Details section or even if it could just be added to the Notes field that already exists.

Bonus points if you could add a way to skim boolean fields visually in a pre-game preview instead of just text:

• Buildout Line: ❌
• Heading Permitted: ✅
• Punting Permitted: ❕
