Copy first record to all in other rows in data grid

I have a data grid with columns like: Name, Start date, end date, description Now if i select start date and end date  in first row, i want it to be copied down to all the the other existing rows. There needs to be a checkbox somewhere in the grid clicking which would copy the start date and end date fields from first row to others.

You can create a microflow

  1. Create a variable two times==> Store value of the start and End date  respectively you want to do for all
  1. Retrieve the list From Database
  2. Use a iterator 
  3. use a change object in the iterator
  4. in change object place that value  (Name of Create variable )
