Production tasks as "lines"/duration in calendar instead of just start and end.

I need to better see which tasks I am currently working on, meaning which tasks are starting today or have started in the past and the end date is in the future (or today). 

It has happened several time now for me that a task deadline shows on the dashboard but the task requires several hours of work (that I don't have today). The start date of the task is very important, however if the start date is "yesterday" in the calendar view, it will be out of sight/out of mind again.

I would like to make this visible in the calendar (i have a view for "production", focusing on the tasks and less on the deadline of the items). The most visual thing for me would be to have the tasks as "lines" as you can do with campaigns.
