Hi Leo,
This is the same problem I found, and after listening to multiple DSR seminars I wanted to execute on the theory but couldn't find the simple tools for volunteers to use. So I built one.
It is actually built with my 60+ year old mother to use, so it is super simple and as it's in the cloud so everyone has the same information and on the same page. This also equates into a succession plan which clubs never think about.
Anyway I don't mean for this to be an advertorial but as it was built out of similar frustrations to what you are having I thought you may be interested. You can email me isaak@tidyclub.com or find out more through

Cheers, Isaak
