Baselines for newly added tasks?



Is there a way to use the baseline function for any task that is added to the sheet AFTER the baselines have already been added. For example, the original timeline was 10 rows of tasks. We have 5 new tasks to enter into the timeline. The only option is to "Reset" the baselines, which I do not want to do since the data on the original 10 rows is accurate.

How can we utilize the new baseline function for newly entered tasks on a sheet that has already had baselines entered?
