Ability to re-run scripts to update scripted attribute values

"Create Nodes Scripted Attribute" is an extremely useful feature.

It would be even more useful with a very simple addition: The column created with a scripted attribute should have a "Refresh scripted values" option (just under "Modify column") that would re-evaluate the function. Currently to do that, one needs to delete the column and recreate the attribute by entering the script code again.
