Ability to Attach Files in Workfront Planning

Description - Would love to have the option to attach a file to a request in Planning.

Why is this feature important to you - We thought we had a solution to our public facing request problem through Workfront Planning's ability to create public request links. However, the inability to attach files makes it a non-viable option for us.

How would you like the feature to work - Just like in Workfront Core, we would like to have the option to attach files to requests.

Current Behaviour - Currently there is no file attach option in Workfront Planning.
