The idea: When creating an Update Request for a parent row, allow the selection and inclusion of Children rows.
When creating an Update Request, you can specify which columns you want to include in the request. I recently encountered a situation where I wanted a user to update a section of rows (Parent + 5-6 Children). In this situation I am unable to include multiple rows in the request. I would need to create an Update Request for each row. I think adding a Parent/Children functionality could be helpful.
Came here to look for a solution to the same issue. This would be a very valuable addition.
Mine is the flip side of the coin; be able to include parent rows when updating children. A number of the activities in Child are similar within the sheet and being able to include a Parent row for context would allow for automating the requests. Have to do requests manually now, which is time-consuming.
I'm here to echo the same sentiments :(
