For example i want to transfer the Cd attribute, but want the Cd to keep the color value once it's been transfer , so if i then move the source object away, the target object still keep the value of the Cd.

How can i do this ?

After doing the transfer you could lock the node ( ctrl + left click ) that now has the transfered attribute.

Then you could remove the source from which the transfer was made.

In the hip - sphere1 and pointwrangle1 can now be removed.

Or a solver sop.

Def go with the solver sop. Inside, add the color of the previous frame to the color at the current frame.
