A few simple tests:
It seems that only one master DocText Macro is needed.
The Macro can be right click MacroSelected to the canvas multiple times, and each canvas copy can have its text modified in different ways, and the canvas .nod program saved in a node program.

But the modifications permute the order of the text lines, which is not good.

Edit: Macro Import can import the DocText file from some other directory.

Note, the order of the text lines can be changed by Max' addition a few years ago of the ability to Alt+Drag the input Dots to the Macro. (I had forgotten this.)
