[FEATURE] Perspective: Add option to copy property values *and keys*

Often I’ll have a bunch of properties that I want to copy and paste to another component, but currently it’s not easy to do. You have to first create the property keys and then individually paste each key’s value from the source. It would be great if we could multi-copy (or at least single copy) the property key(s) and value pair(s), not just the value, as a separate context option from copy value.

Note: I know you can multi-select components and then add keys and values which will apply to those selected, but that’s not useful when you already have the properties and values defined on a component.
