Did you ever find a vendor to solve your particular issues? Full disclosure, I work for a company called Truthlab, which builds research repository software. After talking to many UX teams I've seen a variety of solutions including:

1. Google sheets / google drive
2. Evernote enterprise edition with some heavier up-front work
3. Confluence, but usually grouped by product
4. Homegrown data warehouse

Happy to discuss further if you'd like.
