Employee Self Service Attachments

Hi,

Employees can attach documents (Birth Cert etc) using Employee Self Service under Update Benefits page. This page has only one document category listed - 'Miscellaneous'. This category is available from multiple forms and others are able to see these documents from PO,AP Etc. I am trying to create new category 'Benefits Attachments' and make it available in this form and benefits core forms. I am trying to find out what Form or Function that new category needs to be assigned to so that it is available from list of values in update benefits page of self service.

I have created Document Category from Application Developer -> Attachments -> Document Category. I need to make it available in Self Service. I am able to view it in core forms.
