Creating mix-n-match manuals from a single repository

[FMEEvangelist]

Hope this is a good place to suggest/ask this.

Currently I have a repository with file1.md, file2.md, file3.md, etc which are the files for a training manual, and summary.md for Gitbook.

Gitbook (I'm using the online version) creates a book from this perfectly.

But, say I want to create a second manual as well - perhaps it only includes file1.md, file3.md, file5.md, etc - is that possible? ie I want to create two (or more) different books from one set of md files

1. I could clone the repository, but then I have two copies of all the md files
2. Can I create a second repository with only a summary.md, which points to the md files in the first (eg * [Introduction] repositoryA/CourseIntroduction.md?
3. Ideally I'd be able to have multiple summary files in a single repository (summary.md, summary2.md, etc) each being a different book layout. Perhaps that would be a good enhancement?
