Since no-one else noted this: this is a bad practice. It is much safer
to add one key integer column throughout your analysis. The code to
link one column is easier than linking two columns, you can adjust a
coordinate should it be needed, you can handle overlapping points and
if you save your data/open in other software you are much more sure
that you can still link it.
