[Feature request] Email attachment to document

[SpeedBullet]

Hi, it would be a nice feature to be able to turn email attachments into espocrm documents. An example usecase: I've made a business proposal or contract and sent it via mail to my customer. He agrees and mails the signed document back. As espocrm already imports emails into the CRM, it would be useful to have a button next to the attachment "generate document" or something similar. Then that document gets stored separately as well.
