Genetics cross using 5 loci

Is there anyway to calculate a punnett square with 5 or more traits quickly?

Say, AaBbCCDdEe x aaBbccDdee

Punnet squares get unwieldy for more than two genes. You won't get a question which tells you to list all possible genotypes and their frequencies in which you have to use a Punnet square. You will be expected to find the frequency of a particular genotype in the progeny. For instance, in the cross AaBbCCDdEe x aaBbccDdee, find the frequency (or probability) of the genotype aaBbCcddEe. Just treat them as a bunch on singlegene Punnet squares:

The probability of the offspring having the genotype aa: P(aa) = 1/2*1 = 1/2

The probability of the offspring having the genotype Bb: P(Bb) = 1/2

The probability of the offspring having the genotype Cc: P(Cc) = 1*1 = 1

The probability of the offspring having the genotype dd: P(dd) = 1/2*1/2 = 1/4

The probability of the offspring having the genotype Ee: P(Ee) = 1/2*1 = 1/2

So the probability of the aaBbCcddEe genotype is P(aaBbCcddEe) = 1/2*1/2*1*1/4*1/2 = 1/32
