Currently, plate maps can only be registered manually when creating plates with the requirements of each user. You can find more information about this process in the Help Center > Signals Notebook > Working with Information Items > Working with Plates.
In addition, there is an idea in our Ideas Portal about the possibility of importing plate maps in CSV/XLXS format. We invite you to view this idea by clicking on the following link Importing CSV files to Plates | Revvity Signals Software Ideas.
