Multiple runs at each condition in a within-subjects design

Im JMP 13 Pro --- How would you approach a data set with two within-subjects variables where there are replicates within each condition cell. Let's say Variable A has 2 levels and variable B has 3 levels... equaling 6 conditions. And for each subject at each condition I collected my DV at 10 points in time...let's say i was interested in the measure -- in general -- across the time span but not neccesarily interested in the effect across the 10 time points. I could average the 10 points and use one score per subject per condition...but it there a more elegant way to take advantage of the multiple runs in my analysis using the capability of JMP 13 Pro? Thanks...Geo
Within Fit Model, the Mixed Models personality (available only in Pro) is probably best equipped to handle this type of model because you can choose a correlation structure for the covariance (sounds like an AR(1) structure would be a good place to start).
