Use the set velocity block, something like "Attempt to override velocity of event/target entity with (get X velocity of event/target entity) (get y velocity of event/target entity +0.05) (get z velocity of event/target entity)" or something like that, i may have gotten the name of some of the procedure blocks slightly wrong, but that general idea does work.
