Checkbox without Edit in TTMSFMXGrid

FMX TMS FMX UI Pack
1

I want to have Columns with checkboxes only and no edit field. Is there a way to 'disable' the editor and only have checkboxes as cellcontrols? If I set the cell to ReadOnly the checkboxes are also disabled and there is no editor type 'none' 

Does anyone know how to achieve this?

Thanks

Checkboxes without additional editor can be added with     TMSFMXGrid1.AddDataCheckBoxColumn(3);
