Split the Project data base
The big 8 column batches can be a challenge and not everyone has the time to index the entire batch.
How about splitting the Project when there are large data batches? Put the smaller batches, 400 or less names, in the main project title group and the very large batches in a sub group, i.e. Part C, for the smaller batches, and Part C-1 for the big ones.
Just a thought.
