PTCSGRID widget row scrolling

I have thingworx 10.1.1

I would have on PTCSGRID the same behavioud of previous DXGRID

The case is when I have set a single row selection 

when I scroll up down with the arrow keys, I would like that the selected row changes automatically.
Now instead, when scrolling, I see a border over the scrolled rows but it is not selected ! The selected rows stays on the last position. To select a new row I can press space bar (over the scrolled one) or click with the mouse on the new row.

It is so easy the auto select row when scrolling … 

A checkbox “auto select row when scrilling” on the widget could be OK.

Is there a way to do that with CSS on the page, to avoid waiting for a new release ?​​​​
