Create component based on another


I found a component in the online library that almost matches what I need, but I need to change it a bit and would then like to save it to another part number. How can this be done?
Specifically, I would like to start from part SMTU2032-LF and would like to create a slightly bigger one from the same manufacturer, namely SMTU2477N-LF.

I could not find a duplicate function or something. Please help.

From the part page (ie:, there’s an “Open in Editor” button. Beside that is a little triangle to reveal another option to copy the symbol and footprint into a new part. However, you will have to fill in the attributes for the new component.
