Feature request: Integrate output into markdown file

[RenatoLopes771]

A button besides run that would put the output of the program into the file (next to where the code is written on the markdown file), or updates one if it already exists.

Another feature is to only do this if the program doesn't given a error.

I would also love this feature. I could help on it, if you can provide some guidance.
