Summary

Justification

request from Judi M in July 6 2022 meeting

• Add filtering by category to distribution export, please. Would considerably speed up required reporting

Details

Add another filter to the distributions view This needs to also go forward to the export, of course. Note that the # of items needs to be the number of items for things in the category, rather than the total items in the distribution. The value of the items needs to be adjusted accordingly.

Things we should know

This would be well-paired with issue #3069
