Minor question about Rotate3D!

Hi, all~

When I use Rotate3D component, there is one slot called 'Rot3D.X(Vector)' for the Axis of rotation.

I know I can use a vector component to connect this, and also use 'Set one Vector' in rhino environment, but just wondering can I access using 'Manage Vector collection' and change value directly? for example, default is {0.0,0.0,1.0}, then I tried to type it {0.0,1.0,0.0}.

I changed this value, and pressed 'ok', but the value wasn't changed, still show the default vector value....

Give me the idea~~

Thanks!!
