Importing files larger then 5mb

Please up your maximum file size for attachments (documents & photos). Currently you cannot upload a file larger than 5MB to attach to an email which is extremely inconvenient when you have well-designed trainings with multiple screenshots. Even after compressing my 13 page training it was 5.7MB, still too large. A simple Gmail account allows you to upload attachments that are up to 25MB, so only allowing for 5MB is very low. It's even more frustrating because our company is only using 9% of it's total available space, so there's plenty of room available for a couple larger attachments.
