Create an "Assignment" view (Project>Tasks) where assignments can be edited inline

I would like a way to edit planned hours at the assignment level:

task > multiple assignees > different hours per assignee

• PM = 1hr
• Dev = .5hr

Now the scope changes and we need to double the time

• PM = 2hr
• Dev = 1hr

If I just double the planned hours at the task, Workfront simply divides the planned hours evenly across assignees.

For a PM who runs several projects, on a client that causes such shifts at least once a week , doing this currently in WF is super time consuming - in list view everything' would be right there and editable. The workaround easily doubles if not triples time spent on this

I am looking for an efficient way to edit allocation on a task, something like this:
