I haven’t found a way to push a custom field to multiple projects. But there needs to be a way. If we have 50 projects, I don’t want to have to load the custom field for each one. While I can see that sending to all could be a problem, I would love to see a multi-selection of destination projects.
Also, it would be awesome to have a way to multi-select custom fields, and then multi-select the projects I want them to go to.
