even I messed up how to show communication for the next period, if it was not there yet ....
We show by default for the week - from the current day and a week ago (from left to right, that is, the first number is the current day, and then decreasing)
Sample report
https://docs.google.com/spreadsheets/d/13MCERrjP7Qk8A5-7iy9hLrulBS8J26cjPzKpQB4n...That is, we can specify which contact fields to show, their location
https://prnt.sc/vrbo38+ You need to write in the date cell the value from the additional field of the process that went through the stage (as described above), that is, not just color the cell, but additionally take the value from the process field if it is filled in on this date.
If we manually make changes, they must be saved.
At any time, you can open a report, for example, for the last year and there should be information for that period (if then the data was filled in the box, of course)
