Add bulk edit or cell-by-cell edits to all list reports

I need to bulk edit custom field data in a list report of workspaces (more broadly, in many list reports not focused directly on epics or features). I want to multiselect rows and edit, and I would really like an grid like report view that lets me directly edit cells (aka jira structures views). My painful alternative today is to open each of 100+ workspaces and then edit custom fields. My underlying need is to generate useful business intelligence on Aha! usage by workspace, which is missing part of the features as well.
