Layout in radiobuttons

In the example of TAdvStringGrid, Example 12 : Using radio button inplace editor, the radiobuttons show their captions on the right of the button (horizontally aligned).
I have 5 radiobuttons with 2 captions (far left caption: Low, far right
caption: High).

Is it possible to set the far left caption on the left of the button and the far right caption on the right of the button. In stead of all the captions on the right of the button

So

"Low" O O O O O "High"

Instead of

O "Low" O O O O "High"

This feature was implemented.
