I'm not sure if there is or not, but in the past I have managed this by
creating an ERP dataset that is all zeroes, and then comparing my real
dataset to it with a cluster test. Since a one-sample test is the same as a
paired samples test between something and zero (e.g., comparing X and Y via
t-test is the same as comparing {X-Y} to zero), this should give the same
