What type of request is this?

New feature idea

Clear and concise description of the feature you are proposing

I'm running the pastebin on multiple domains. It'd be great to be able to provide those domains as a list so that when the note is created, we can select under which domain we want to share it.

Additional context

Something like a drop down that changes the copy to clipboard link and generates the correct QR code for the domain.
