Partial Filtering on CAN RL-ARM library

Hi,

How can I use CAN Bus acceptance "partial" filtering with the RL-ARM library for LPC2478?
I know the use of CAN_rx_object (0, 0, 0x21, STANDARD_FORMAT) function that could be perfect
but it applies a filter for ALL bits of ID.
How can I filter only some bit of the ID? To justify this you can think on j1939 protocol where in the 29 bits could there is the destination address but also some bits that are something like a "command" that it often changes its value.

Thanks in advance for any suggestion.
