Thanks Rob, I understand what you’re looking for here. To be completely honest, I don’t think custom fields with the daily batch readings is the right solution, however. I think this would better be covered by batch schedule events:
If these batch schedule events could be “ticked off” when done this would probably work well for you and would allow us to also show those outstanding in a list much as we do with the daily batch readings.
If you’d agree with this, could you give that other feature request a vote too, to push it up the priority list?
