Count number of attachments per feature

Hey,

The Multi Feature Attachment Control should support a setting to display the number of attachments listed per feature.

It should also be possible to create a Calculated Field on a Data Source that counts the number of attachments per feature. I can't find any relevant expressions for this today, but I might be wrong. 

This process is usually done via Workflow, but it would be beneficial to gather this information in Reporting only. 

Thanks,
