I’ve asked for this as well. Until we can increment of value in a different sheet, you have to bring in that value into the current sheet using a single relation and look up column. Then, create a math column to provide the increment you want (usually plus one). Lastly, use the set column action (instead of increment) to overwrite the “minutes” column with the value from the math column.
So complicated…being able to increment over a relation column would be so much easier! @Mark
