Supervised call display on 9 series sets

[tjm0852]

Can I somehow program a 4029 or 39 set so that if a number I superivse rings I will be able to see it? In other words I need to see not only the CLID of who is calling but what extension that I supervise is being called. This is currently an issue if I am already on a call, I cannot see who's extension is ringing. Obviously this can be done on a 4035 set because I can look at the key flashing to determine which extension is ringing. But I have not been able to find a way to do this on a 4029 or 39 when a call is already in progress. Does that make sense?

The end user supervises multiple numbers and on certain days only wants to answer calls for user x, but not user y. How can they see who is being called if their set is in use at the time of the call?

while on a call you can revert back to 'idle' screen by hitting back key (the silver button).
But in the future any users I have that need supervision keys I throw in a 10/40 key module.
