Macro for importing custom properties from a text file

Does anyone know of a macro that can be used to import custom properties from a text file.  As people approve a drawing we have them use a little program where they put in their initials and it creates a text file with their initials and the date in the same folder as the drawing.  I would like to be able to use a macro to grab their initials and the date and input them in the custom properties for the drawing.  Any help with this is greatly appreciated as I am very new to the idea of using macros.

The text file usually contains three initials and three dates. the program that creates the text files can be modified to put them in alphebetical order or some order that allows the macro to distinguish which one should be associated with which property and the properties that they would need to be associated with are checked, checked date, engineer approved, engineer approved date, QA approved, and QA approved Date
