Is the plan to use the basic poison from the PHB? That kind of poison only lasts 1 minute once applied and is an action to apply. So by the time poison has been applied to the last dagger the poison on the first dagger has expired. You can of course get others to help you apply poison. But because of the time limit it requires knowing that a fight will occur within the next minute. It's not something you can always have ready in your back pocket.
