How to Achieve "POPIN in TreeByKeyTableColumn" ?

Hello,

SAP online help for NW 7.01 say's its not possible to have cell popin's in TreeByKeyTableColumn

[http://help.sap.com/saphelp_nw70ehp1/helpdata/en/fc/501b42b5815133e10000000a155106/frameset.htm]

But is there a way we can develop using POPIN without Table POPIN funcitonality or is there any other simple work around ?

Thanks in anticipation for your responses !
