There has been an update to FLOW where you know have to go into the storage tab to adjust the porosity, the base coeff, the Side coeff, the surround shape and Diameter. (say for a filter drain)
You used to be able to change all of this from the sketch tab when you expend the infiltration box, once you have selected a link. Now this feature has been disabled and it is a headache to switch back and forth between the Sketch tab and the Storage tab to manually change them for each link.
And to make it even worse, say you have multiple filter drains leading to a manhole with different diameters, you have to know the link name for each incoming drain. So you have to go back to sketch to see what the pipe name is for each.
It was much easier before when you could do it from the sketch tab, because you could see what link you were selecting
