Adding fields to approvals

Adding fields to approvals

Hi,

I am getting the CRM to work how we need it to, however one thing I would like to work out is something on the approvals process.

My sales team submit deals for approval with a checkbox on the potential tab. Then I get an email asking me to approve. however the approval screen and mail only shows the potential name and requester.

Ideally I would like the approval screen to show some additional fields, such as total value and Margin (one is a custom field)

Approvals doesnt show on the dropdown on the customisation section.

Is there something I am missing?
