Good morning everyone,
I am trying to group values in a dataset when consecutive entries meet the same conditions. The problem is that my data is organized by date from newest to oldest, and I can't really change this because of other formulas. This means that I cannot use the MultiRow tool to reference the same column with the row below (row +1 on desired output column), as it seems to only work with row -1.
To be more precise, I attached an example of what I am trying to do below from my excel file: for one particular product, I flagged the start of a "collaboration" period and the end of this collaboration period in columns Q & R with "Yes". What I would like to get is the columns T & U on the right: returning the same value (i.e. the start date and end date) for all entries across a collaboration period, meaning a period where there have been collaboration events consecutively.
Alternatively, I would also like to know if it is possible to get the column S, meaning the number of consecutive collab events in reverse order (as my data is organized from newest to oldest.

Let me know if there is a smart way to do this, that does not involve changing the order of the dates. Thanks a lot for your help!
Best regards,
Romain
