There are two aspects to this, the first is a person being able to see all the approvals that they can make, this should identify the pipeline execution and approval name with a link to approval step.

The second is being able to select one or more of the entries and approving all selected entries.

As to the pipeline executions, they could be from any pipeline that the user can see and could also involve multiple executions of the same pipeline.

Can you please help me clarify on the below:

What do you mean by bulk approval? Multiple approvals across multiple pipelines or across same pipeline but different executions, or any thing else?

Thanks!
