Restriction on no of attachment and size of attachement in appraisal documents

Hi All

I am working on Performance and Talent Management in EHP 6 environment and have a query regarding attachment that can be uploaded in the appraisal documents.

Can we have any restrictions on number of attachments that can be uploaded in a performance appraisal document

and the size of the attachments.If yes than how can we do that. Please guide.

Thanks
