Yes, to add information as more information become available is a good workflow. In some cases number of choices later on is fewer for example an MCU then symbol have been selected there usually only are a few different symbols to select from later on. Another reason is quite often the perfect solution is not selected from the beginning so then you discover it is time to choose another symbol you have to thru away less time spent if start is fast.
