Limiting Attachment size in ALM?

Hello All, We have an issue where we are grown the data considerably because we are attaching lots of screen shots and files to the entities within ALM (test cases, defects, and requirements). Is there a way to limit the size of an attachment that we can upload to these entities? We have a requirement that the users attach smaller files sizes but lately have found some aren't following these guidelines and we would like to be able to limit the sizes that can be uploaded until a time that we can better archive and obtain more free space. Is there and easy way to do this through workflow or otherwise? Thanks, HomerJ
