Mark tasks that are "carried over" from the previous day

[slaFFik]

Sometimes I feel ambitious and create a bunch of tasks for myself for the day.
On day 1 I complete them all, and nothing is moved to day 2.
On day 2 I was motivated because of day 1 performance and decided to add even more tasks. But I failed to finish them all and...

Current behavior

... those tasks are moved as is to the next day.

Desired behavior

... those tasks are moved to the next day, but a new prefix (co) is appended.
So on day 3 I will see a task: (co1) do something special, where (co1) means that it is a "carry over" for 1 day.
On day 4 for that same task: (co2) do something special - carry over for 2 days, etc.

Having a visual indicator of the task history would be helpful to nag myself to finally do that something special thing.
