Connecting P6 with Submittal Log and Schedule of Values - any good ways or spreadsheet systems?

Connecting P6 with Submittal Log and Schedule of Values - any good ways or spreadsheet systems? - These items are intertwined - one of the worst things you can do is make the schedule into either a submittal log (or a to do list).  But how to you efficiently feed the info between them - surely P6 has addressed this.  I think years ago they did with their Old CM tools (ie Expedition - yes I am old.) but by getting fancier I think that easy link was lost.  I only see them excel now days.
