Hi Yusuf,Thanks for getting back to me on this.The data sets I have will have between 3 and 6 different cell flags in them. So, for example, if there are 1,000 records in the data, 250 of them will be marked with a Cell ID of '001', another 250 will be marked with '002' etc. Currently, I will split this data set and send each sub-set a separate delivery, but I wanted to try and keep the data as a single set, so the label is defined dynamically, much like you can with the Analysis tab of a Recurr...
