"Load" not an option in Reclassify tool

[ClaireWayner]

Hello, I am trying to complete the online tutorial on Least Cost Path calculations and have run into an issue with my Reclassify Tool. There is no "Load" folder option next to the "Classify" button under my table (see screenshot below). Thus, I cannot upload custom values. I am using newly installed ArcGis Pro 2.5. Help?
