Our Wrike workflow has been designed a bit differently than the norm. We use Tasks as deliverables or projects, we do not use Projects (because it was easier for the team to see all of the deliverables a department has requested as a list of tasks. (Departments are Folders, and the tasks within are projects & deliverables).
lf there are multiple deliverables in an ask, we use subtasks and the top level task becomes a "Folder" (which is assigned a custom workflow status as such, so that we can filter it out of reports).
Because we don't use projects, my current way of knowing who the project lead is, is to assign the lead to the task itself, along with the other people working on the deliverable. It works fairly well, however, it would be ideal if tasks could have their own "project lead" field (or call it "task lead") that would allow me to + add people similar to the assignee field, and separate the information for better reporting and clarity.
