Yes, you can do this directly in calibre without using Action Chains:
- Filter out the books that have blank value using the following search:
Code:
#kobo_read_date:false
- Select all the books resulting from the previous search, and then use calibre metadata edit to set the kobo_read_date to current date by pressing the "today" button next to the kobo_read_date cell in the bulk metadata edit dialog.
If you still want to do this using the plugin, you use the search above as the scope for a single field edit action that sets the date to current time.
