Does prompt-toolkit have clipboard buffers?

[Spitfire1900]

I use Xonsh and they directed me here as it uses prompt-toolkit underneath.

I frequently with copy a string from an IDE or web browser to paste it into a Xonsh session in VI mode. I'll use normal mode's c+w or d+t+<char> prior to pasting. This overwrites the clipboard buffer.

is there a good approach to keep buffers separate so deleting/yanking in prompt-toolkit does not replace the system clipboard?
