Changing EP Cadence without Losing Reporting
We have an Engagement Program that sends casts every two weeks. We had to pause it for a couple of weeks and now I've been asked to start it again on 11/19. Because the first cast was on 4/29, no cast will go out on 11/19 unless I, effectively, re-set the cadence and change the first cast to from 4/29 to 11/19. I am reluctant to do this because if I do so, I believe I will lose the Engagement Stream reporting for casts that occurred prior to 11/19. Any ideas on how to get the next cast to go on 11/19 (and every 2 weeks thereafter) without losing the prior Engagement Stream reports?
(I know I could use Email Reports instead but there are so many emails in the stream it would be much easier to use Engagement Stream reports).
