I am looking for an option to run a filtered time report, that includes custom fields. This would make the billing process so much smoother for me, as some of the billing rates are dependant on the custom fields. Right now, I need to go through each row manually and check if the conditions apply... which takes up so much time! And cross-tagging everything into a special folder, just for this report, is taking a lot of time as well and also creates unnecessary spam in the "location" info within the item view.
TL;DR: Is there a way to filter time sheets/time reports by custom field?
