Is there a way to calculate the average peak % area of peaks greater than or equal to a certain threshold (e.g. greater than or equal to 0.05%, or GTE), peak by peak, between two samples and then sum those peaks on Empower (e.g. AVE(Peak1inSample1[PercentAreaGTE05] + Peak1inSample2[PercentAreaGTE05]) + AVE((Peak2inSample1[PercentAreaGTE05] + Peak2inSample2[PercentAreaGTE05]) + ...), possibly using custom fields with boolean expressions?

to solve the GREATER than, you can make a customfield which multiplies your result with the GT function:
if it's greater, your value is multiplied with 1, so your result stays, if not, your result is multiplied with 0.

if it's greater, your value is multiplied with 1, so your result stays, if not, your result is multiplied with 0.
