Hi Vladyslav,

I am generating a two-loop amplitude with FeynArts/FeynCalc with the development version
and I noticed that there are things generated as

IntNEW = FAD[p[1] + p[4], p[1] + p[4]]*FAD[q[1], p[1] + p[4] + q[1]]*FAD[q[2], -p[1] - p[4] + q[2]]

and before one uses to have

IntOLD = FAD[p[1] + p[4]]^2 * FAD[q[1], p[1] + p[4] + q[1],q[2], -p[1] - p[4] + q[2]]

Is there are way to pass from IntOLD to IntNEW?

Many thanks for your support,
Will
