Bulk Delete Members

On OpenPlace, there is a solution named Unused Member Analysis (UMA) which allows a user to view members across the dimension types which do not have data. Additionally, you can check whether the members have annotations (text) written against them. For any members which do not have data, you can delete them in bulk from the solution.

Hi, I have been using this solution but it times out for many of our dimensions. Hence the bulk delete is not possible. Is there a way around that?

I have downloaded the dashboard, and there is no delete in bulk button... this does not work.
