Generic CAN Paged message grouping

I have run into an issue while trying to read NMEA2000 data from 2 engines. The message uses pages to transmit data across 4 messages and has an engine instance in the first page. I cant mask for the engine instance in the last 3 pages. 

It would be nice to have a multipage option like the J1939 Frame for NMEA2000 messages. If that could be combined with masking for instance value, that would solve my issue.
