average past results?

[sothisiswhereitis]

Hi Guys
is it possible to average past results rather than live results. for example i have 3 measurements loaded i made some time ago, actually they were made in a different programme and imported as frd files. Now they are loaded in rew is there anyway to merge them as an average result and save that? thanks.

Sure, use the features of the All SPL graph.
