Annotate a MatrixTable with rows from a different MatrixTable

Is there a way to do this? I have two MatrixTables for the same cohort. One of them has already gone through filtering to pull out variants of interest, whereas the other is unfiltered but has many useful annotations (MetaSVM, CADD, etc.). I would like to annotate the filtered MatrixTable with those additional annotation rows from the unfiltered table. Is this possible?
