Sketchup for web saving components

Can I save a component in the web edition? If so how do I save one?

Create it it in a separate file and save it or upload it to your 3D Warehouse account.

I want to save component with right click and reload it, as desktop version can.
Can I do with web version?

When double click the component and select all contents, copy and paste it to new file, the axis origin is global not local components axis.

I want to copy components contents to paste it to new file to local compponents axis, can I?

No. Not currently anyway. Maybe someday but who knows?

Thank you for your rapid reply!
I could understand one of several differences between the desktop and web versions.
I will substitute it by pasting component to the same place in new file.
