Maya Rosman posted a similar idea for Query, and I'd like to pose the same for Reports.

Currently when you want to add a filter and use "one of" from a table field (like Fund ID, Appeal ID, etc.) in webview Reports, it loads a single list showing you checkboxes for all the fields you have selected.

With a large list of Funds, this is not a functional way to access the information. The system will not even load our entire list of Funds. The scroll bar is essentially useless because it stops after so many records, and when it gets to the bottom it begins again from the top of alphabetical order rather than displaying a continuation of the list. There is also not even an option to "Load More" like there is in query. With a scroll bar I would expect to be able to access the full list in some way. When I contacted support, they said it was meant to function that way to improve performance by preventing the system from loading an excessively long list of funds, which can cause slow loading times. I would argue that it will take much longer to have to create and edit a query or use the search feature each time I want to run a report and make sure I'm including (or excluding) all funds needed. I'd rather wait a minute for the full list to load. Even the ability to choose how many to display on screen and the option to "Load More" after that to see the full list would be a help.

As Maya said for Query, "ideally, the UX would be adjusted to behave more how database view query worked, with a side by side list where your already selected table entries were on one side and your unselected table entries were on the other side and you could easily move entries between the two lists as necessary. Both of these lists load fully, and the unselected entries are searchable. This allows for quick decisions and easy checking that you've selected everything you need, going in and out of search without having to reset everything time. This is a case where the new interface is actively working against functionality and I would love it if it was adjusted to better support user's needs."
