Attendant speed dials based on status?

[Sage Major]

I have a 504 with a spa500DS.

I have lines setup

<Unit_1_Key_1 group="Attendant_Console/Unit_1"> fnc=blf+cp+sd;sub=18@$PROXY;ext=18@$PROXY;nme=Robert 18 </Unit_1_Key_1>
<Attendant_Console_Call_Pickup_Code group="Attendant_Console/General">*12#</Attendant_Console_Call_Pickup_Code>
<Server_Type group="Attendant_Console/General">RFC3265_4235</Server_Type>

Currently when the line is receiving a call (flashing red) I can push the button to pickup the call, based on the Attendant_Console_Call_Pickup_Code setting.

 When there is no call (green) pushing the button will dial the ext

When there is an active call I would like the ext to be pre-pended with *47

Is there a way to treat an active call differently than no call with the button push.

When there is an active call I would like the ext to be pre-pended with *47

It is treated differently already - with active call it cause pickup, with no call it cause dial. But no, it's not possible to define another prefix for speed dial (as far as I know).
