How to set the same value for some posts on the same time
Binded editing feature will help:
- Select first post you need using checkbox in the most left column
- Press SHIFT button on your keyboard and without releasing it click on the last (last by your logic) post checkbox
- On the tools panel enable ‘binded editing‘
- Enter any value to any field of any selected post you need
- Wait until operation is finished
Hint: really this operation is bulk editing, so you can cancel it in tab Bulk Edit and then roll back it in tab History
