By default, multisynth() and others use the mean of the covariates in the pre-treatment period to construct the synthetic control. If I want to take the average of the covariates every 3 years (for example) in the pre-treatment period, I guess I should use the argument cov_agg but I didn't find any examples in the docs or in the vignettes and the description of this argument is not very detailed.
