Show Task Details on Sign-Up volunteers overview

It is very nice with the “column visibility” chooser on the Sign-up overview (even I could wish to keep my choice of fields to stay more permanent).

But I really miss the column Task details/description field in the choices?
To illustrate my problem, I did two screendumps.

The public Sign-up has a nice overview: Compact and with details written in Descriptions column:

But on the Backend Sign-ups details are the Task details not available:

I have tried to add more description to the Task title – but then the GROUPING is not working.
This could work if there are dedicated fields for “group name” for each task,
but just to add the existing Descriptions field in the Sign-Up overview would do for now.
