Daily prices for the extra price rows can be sent to specific rates by including the additional rate code after a colon.
For example the rate code '''1111111A/D:1111112A/D''' will send daily prices from price row 1 to rate 1111111A and daily prices from extra price row 2 to rate 1111112A.
Normal rates with no overriding rate code will be set to the first code 1111111A.
