Unless there is an external storage capability or hack I don't know about, there are no external storage capability for the Pioneers.

I end up using paper/pen/index cards and type programs on the computer for a storage. For most of the calculators, the programs and user formulas are responsibly small to do so because they can entered quickly. I think the 42S and 27S can use the infrared printer.
