Hi,

We are using Custom Object inside our projects. We can add new person as a reviewer to the projects using dataloader which gives them permission to view the project data. But is there any way to provide permissions to custom object using dataloader directly? We have created a custom action for now but there is a limitation that it will take 50 rows at a time and we have to click multiple times to provide permissions.

If  this is possible then please share a sample for dataloader file. I checked the fields but not sure how to provide viewer role.
