ability to include wildcards when defining book chapter targets

Hello,

I keep a journal of separate .md files, where the file name is just the creation date of each .md file. I just tested rendering it after using the create-project <name> --type book which is nice, but it doesn't look like wildcards can be used in the chapters option in the .yml file, akin to how it works for projects (see: https://quarto.org/docs/projects/quarto-projects.html#render-targets)?

Since I don't keep a daily journal and I have a growing number of entries I'd like to avoid adding the chapters manually. Could wildcards be added or are there other ways to automatically identify all .md files in the book directory and render them?

Start with the linked discussion and the book project's chapters option in its .yml file. Investigate how chapter targets are resolved and how wildcard targets work for projects. Done means a book can identify and render matching .md files without listing each chapter manually.
