Use ROS2 param to update node parameters from YAML

edit

I'm trying to tune parameters that I load from a yaml file into a node. Once the node is up and running I'd like to modify my yaml file and load the parameters from the file into the node without having to restart the node. I looked at ros2 param set but it only allows setting a single parameter and there seems to be no way to updated a set of parameters from a file. In ros1 there is a load command that would let you do this but it seems that there's no equivalent feature in ros2
