It is very easy to get into the Initial Estimate screen, and once that happens, the field is set to a value other than blank. However, there is no way to remove that configuration once I get into that screen initially. I would like the ability to clear out the value that was configured or at least not make it auto-save just by going into the Initial Estimate screen.
Thank you for your idea. It is currently possible to remove an advanced estimate once it has been added. To remove it, click on the estimate and then click the more options
... menu. From here you will see an option to delete the estimate. This will set the initial estimate field back to its default state.
