Simple Save or similar

I really don't know why Corel doesn't come with such a checkbox but I miss a functionality to save a file back to the same version it came from. I found this macro:

which hasn't been updated for a while .. I managed to update the versions dropdown but not being so much into programming I rather not continue to mess with that code.

Does anyone know of a similar and updated macro?

Cheers,
Daniel

P.S. I know newer versions have new functions and issues may arise but I have a version mismatch between home and work and I would like to keep my work files in this older version.
