How to fix Power Estimation Confidence: Low: user provided insufficient toggle rate data

In my design, I have a 6b x 12b multiplier that is inferred from code that is essentially if(rising_edge(clock)) then if (clock_enable = '1') then result <= num_6b * num_12b; end if...

Sorry - when I said I don't see a way to import csv to EPE, that wasn't what I meant. I have never had trouble with EPE. My problems are in the Quartus power analyzer, after the design has been synthesized, placed, and routed, not in the standalone EPE spreadsheet calculation. Does that provide any clues, the fact that it works fine in EPE and recognizes the multiplier's internal nodes with the proper toggle frequency but can't after synthesize/p&r in the Quartus tool? My design has to be analyzed by that tool, not EPE.
