I hope you're doing well!

It would be very helpful to have a more flexible way to mark individual posts for invoicing. Currently, the "Mark Time" -> "Invoiced" functionality marks all posts as invoiced, which doesn’t work well when only specific posts need to be mark by us.

To improve this process, I propose adding checkboxes to the left of each post, allowing users to select and mark them individually for invoicing. This enhancement would provide greater flexibility and significantly streamline the workflow for us, especially in scenarios where there are many posts, but not all should be invoiced at the same time.
