+If you want to mark a book as "Ignored" from syncing:
+1. Follow the steps above to add the custom column, or return to the **Preferences → Add your own columns** view & edit your existing column
+2. When you go to set or update the **Template**, click the Edit button next to the field

+3. In the Template: box, paste the following, and press "OK:

+```
+program:
+ if identifier_in_list(field('identifiers'), 'hardcover', '1', '') then
+ 'yes'
+ elif str_in_list(field('tags'), ',', 'hardcover-sync-ignored', '1', '') then
+ 'ignored'

+
+
+4. Find any book that you'd like to flag as "ignored", edit its metadata, and add a tag of `hardcover-sync-ignored`
