external yaml files in header

[wahalulu]

I have a whole bunch of qmd files that share the same output format (reveal.js slides) with a high degree of customization. Is there a way to store the format: part of the header in a separate YAML file (or any other shared YAML block in the header) and include it in the header for each individual qmd? Is there a more efficient way of doing this?

I think either a quarto project or _metadata.yml files might suit your needs. More here:
