I have not, unfortunately.
My procedure is still to either download completions as spreadsheets and upload them as grades or to open two windows, one with activity completion and one with the grade book and manually entering them. It is still a laborious process as some of the activities are marked differently depending on when they were completed (e.g., completing all review of preparation materials before a class discussion is marked higher than completing the review after the discussion takes place).
I'm glad at least for the evidence that someone is seeking a similar solution.
