Yes, but the command will depend on which version of FCP you're using. With FCP 4.5, select the logs to be recaptured in the Browser, then CONTROL-click on their Tracks column and select "1V, 2A" instead of just "1V". Then in the Audio column choose either Stereo or A1+A2 (dual-channel mono).
In FCP5, select the clips and go to Modify - Clip Settings. Make sure audio is selected.
