Wish: Add "Append" option to WriteText node

Append new data to end of text file

Anyone know how or if there is a way to have dynamo append to the end of a text file new data, instead of re-writing the entire file? Or any other file type like .csv, .json, .xml? This would be super useful and right now it doesn’t appear there is any logic for this. I’m especially interested in the ability for two or more different machines to write to the same file without overriding one another. Thanks!
