Reading flat files into strings

I have a folder that contains a set of text files and need to read each file in that folder to create a table with one row per file and two columns: 1) filename and 2) all the text in the file as a string, preserving all whitespaces and newline characters and not trying to interpret or parse the contents of the files in any way. Surprisingly, it seems that there’s no standard node to accomplish this simple task. The closest one I could find is the Flat File Document Parser, but it produces parsed documents, not strings. I have been able to emulate the desired behavior by combining List Files/Folder, Table Row to Variable Loop Start, Line Reader, Group By and String Manipulation nodes, but this seems to be an overkill for such a trivial task. Perhaps, there exist a simple file-to-string node somewhere, but I just could not find it?
