Is there an easy way to look at all the observations you have in a project and then batch-add a field to them? One of the projects I’ve submitted to added a new field they wanted to use, but there doesn’t seem to be a fast way to do this for old observations. I can do one or the other, but not both at the same time.
Unfortunately there does not currently appear to be a way to do this, unless it happens to be possible to exactly replicate the project membership criteria using the available search filters at (in your case)
&project_id= to the search URL generated by that filter does not appear to have any affect.
It seems like it would be very useful to be able to batch edit one’s own observations based on existing membership in a project. So I would encourage you to submit a Feature Request topic to add Project to the filter criteria for batch editing observations.
