Would be possible to use aliases inside .yaml files (to cross-reference rows inside same file)?

I'm trying to use this in order to use .yaml files as Meeting Notes, and then store meetings info into the sqlite db.
Main value it will provide is being able to query which agreements were taken and when they were taken (by pointing the 'agreement_date' to the '&date'), despite of providing other informational session of each meeting.

[meeting_notes.yaml.txt](https://github.com/simonw/yaml-to-sqlite/files/8393529/meeting_notes.yaml.txt)

I'm guessing some meetin_notes.yaml file like:

- meeting_name: weekly
  &date: 20220330
  attendees:
  - Potato Mendez
  - Emily Laughter
  - Paul Bean
  absences:
  - Johny Walker
  - Rose White
  agenda:
  - Topic 1
  - Topic 2
  - Topic 3
  - Topic 4
  session_development:
  - Explanation about how 
  - the meeting has been evolved.
  Agreements:
  -
    agreement_date: *date
    tag: participation
    summary: This is the first agreement taken on this meeting.
    method: consens
  -
    agreement_date: *date
    tag: work
    summary: This is the second agreement taken on this meeting
    method: votation

Thanks all for your work! <3
