We are using Google Sheets to track a list of about 60 people. We add and remove some each week. I am using functions like this to join them into a groups, =TEXTJOIN(", ", TRUE,$A$2:$A$15)
I would like to replace the $A$2:$A$15
part with something that would take 1/5th of the total list regardless of how long or short it becomes. Is this possible?
