Multiple attachments per Document in Secured Folder library

Current situation:

Currently, the Secured Folder library does not have the ability to house multiple attachments. 

Also when configuring a template within a document class (in Secured Folder libraries), it reads The default template can't have an attachment when trying to add an attachment. 

Feature Suggestion:

When configuring a Secured Folder library, I think it is very crucial that a Document has the ability to house 1 or more multiple attachments. 

This is very important for our business need.

Thanks
