Variables for addresses in master.cf

[Daniel L. Miller]

Does Postfix support variables (I suppose defined in main.cf) to be used 
for internet addresses in master.cf?  Example:

main.cf:
   inbound_interface = 192.168.0.10
   outbound_interface = 192.168.0.11
master.cf:
   inbound_interface:25   inet n - - - - smtpd
   outbound_interface:submission   inet n - - - - smtpd
