Attachments and Deadlines for Work Items

**Is your feature request related to a problem? Please describe.**
There is no easy way to place attachments on work items or generate an expected start or end date for tasks.

**Describe the solution you'd like**
It would be beneficial if a space on the work item definition could allow for the addition of file attachments. Even limiting attachments one would be acceptable.

Additional fields for an expected start & end (deadline) dates as well as a priority dropdown would also help users understand their workload and prioritize. If these items can be linked to tasks and/or notifications in the Salesforce org, that would also be great as the user could see those items on their home page.
