Hi Tomasz,
We already had a property to get target elements in cell selection and cell de-selection. In cell selection, we will get the target element in the currentCell property of cellSelecting/cellSelected event arguments. While de-selecting, we will get the target element in cell property of cellDeselecting/cellDeselected event arguments.
Please get back to us, if you require further assistance on this.
Regards,
Pooja Priya K
