can I run a code line (control + enter, not chunk) in the markdown root directory?

Hey,

the title pretty much says it all. I know that I can run code chunks in a markdown document's root directory instead of the working directory, but what about executing single lines from a markdown document? control + enter sends to console in the current working directory - is there any way of executing statements (not entire chunks) in the markdown root dir context? It would make incremental coding of chunks so much easier ....

Best wishes,

Kevin
