Yes, only. Issued SOPs can be partially edited with the "Edit" feature, and when you Issue a revision, it is recorded as "Revision history".
●Replace only the matching sections
When only the model changes or the Target's appearance changes, you can use revision mode to Replace only the Video, Image, and Description of the matching steps. You do not need to Recreate the entire SOP.
●Revision history and Restore
Each time you Issue a revision, the Revision history (Rev.) is recorded. You can view past versions and Restore to a previous version if needed.
