dbc files: PGN instead of ID?

[MarcMiles]

I have a kind of generic dbc-File for a couple of J1939-Messages. As far as I can see, the coding of the messages in the dbc file uses complete IDs, for example 0x8CF0047E. Now I have a machine that uses another source address and changes the priority resulting in message ID 0x0CF004F0, which seems to make the dbc file useless. I wonder if SavvyCAN could do the decoding just using the PGN part, 0xF004 in this case, so one dbc file would be usable independent of results of address claiming and manufacturer specific priority settings. Am I thinking wrong?
