How to set up an external number associated with a subscriber on PANASONIC TDA100?

Question

Telephony

Good afternoon! There is a mini-ATS Panasonic, to which 12 external lines (CO1...CO12) are connected.
Under the current setting, all extensions are equal and occupy outside lines in turn. Is it possible to configure some of them in such a way that when entering the city from number X, the subscriber gets only to the Y line, and when calling to the Y line, the connection with the subscriber X occurs? In this case, the rest of the line pool should not include the Y line.
