Removing duplicate cross-reference entries in an index

[Rajesoz]

Hello,

I have created an index using entries thanks to the "References" menu. For some entries, I used the "Cross-reference" option instead of displaying the current page number.
If two entries are the same, and with the same cross-reference, each cross-reference is still displayed in the index.

Is there a way to remove the duplicate cross-references in an index, without deleting manually each redundant entry ?



My index currently looks like this:

atom, 12, 28
electron, 22, 31, 35
neutron See nucleon, See nucleon
nucleon, 13, 21, 30, 41
proton See nucleon, See nucleon, See nucleon
radioactivity, 4, 11

What I want it to look like:

atom, 12, 28
electron, 22, 31, 35
neutron See nucleon
nucleon, 13, 21, 30, 41
proton See nucleon
radioactivity, 4, 11

Thanks in advance !
