How to get the description of a selected record from F4 help in Personas

Hi,

What i am trying to achieve here is getting the description of a record that has been selected in the F4 help popup window onto a label next to the F4 help in the screen. This is very common in SAP GUI. Example once a vendor is selected from an F4 help, we do see the description of the selected vendor next to that field. Is this achievable in Personas?
