Adjust Output Bus Range for Attenuation Editor

Question

How can I adjust the output bus volume range on the attenuation editor? It goes from -30.1 (when window is maximized) to -200 in an incredibly small viewing range. It makes it incredibly difficult to drag nodes around once you get in the quieter ranges and I rather not type them in.

Comments

When you select a node in the attenuation editor you can edit both x-axis (distance) and y-axis (volume) values by typing them in under the co-ordinates area.

Edit: I just realised you are asking about editing the range... Sorry, I don't think it's possible.

Yea, I usually update these at runtime by dragging nodes until it sounds decent. I run into this problem when I start dragging below the -30db mark. Typing them in isn't necessarily what I want to do.  :)
