Do I multiply charge current by number of battery packs when charging in parallel?

Im trying to charge these 1S3P LiIon 18650 Battery Packs with this battery charger using this parallel connect plate. Can I just multiply single pack charge current by however many battery paks I connect in parallel to determine the charge current? (example: single pack 8A, so 3 packs 24A?)

Also, if the charge current is fixed, would the charge time proportionally divide by the number of batteries I have? (example: 1 battery pack at 6A takes 9 hours, so 3 packs at 6A will take 27 hours?)
