Hello @hm_stella ,
The Notepad functionality is not available yet. Currently, you can only use point geometry with the semi-automated review tools. However, you can create a file geodatabase containing the notepad feature classes for digitizing error geometry and perform your review using the editing tools. In the end of your review, you can transfer the digitized features from your file geodatabase to the Reviewer Workspace using the Write To Reviewer Table tool.
To reuse the file geodatabase with the notepad geometry for each review session, you can save it as a layer package that will contain symbology and the database.
The process of transferring the notepad geometries using the Write To Reviewer Table tool can be automated using model builder.
Thanks,
Paulina
