Did you know that you can now save list completion report views and automate who gets emailed and when? On the top right of your completion report in the web portal, you can save your report view and then open up the settings by using the more options menu (three dots).

From there you can set the schedule and which role(s) should receive the report. Does this help?

it would be nice to pick which reports get sent out in email digest - dont want completion for all list
