In Elements 7 Montage . .

. . .is there any way to normalise individual clips?

Look at Edit > Meta Normalizer

Thanks very much PG.

I missed that in the menus and it is not mentioned anywhere in the documentation according to several inspections and PDF searches.

As such I expected that the feature might not be implemented in the Elements version which would severely cripple the CD mastering features as I see it. Needless to say you do yourself a huge disservice by such omissions in the manual, and I sincerely hope you are addressing this for the next version.
