Is it possible to simultaneously adjust the X,Y, and/or Z values of a key in Cascade's curve editor?

When tuning my vector curves (e.g., Size/life or Velocity/life) in Cascade I often find myself wanting to move pairs of values (e.g., x&y or x&z) simultaneously. Is there a way to select all of the keys with marquee select then move them as a group instead of individually?

I should be more specific as to what I mean by “move”. The desired behavior would be to marquee select (ctrl + alt + lmb drag) and then move them as a group using ctrl + lmb drag

I am having the same problem. If I go to Box select items that have the same value, only the top visible item will get selected.
