This sounds like a good idea.

When considering flexibility to add new output options, then I favor a
new file format that allows extension without breaking backwards
compatibility.
Using the same file format and extend it with an extra column to add
per output options is not very flexible if more columns need to be
added later. The file format is not flexible enough to extend it
safely in that case.
