Recent items : how to get task description

Hello,

I'm looking for the display of the description of a task in the recent items list (to change from the ID into the description of the task).

I read around how to customize the id/description of links shown on Recent items through customer customizing table is CRMC_REC_OBJ_AC. That's what I did.

But as a result after creation of a new task, I get now "Activity Tasks" name in the recent items list while I would like to get the description of the task itself as "call customer for...".

Do I have a chance to display that description?

Thank you in advance.
