This is just a custom UserTag or sub to be called prior to listing the
cart. Over time I have posted many examples of routines which iterate
over the $Items array and change item parameters.

It is easy to make this the default with a special tag, or just by:

[item-list comment="[munge-cart]"]
[item-param foo]
[/item-list]

Any competetent IC consultant should be able to get this going in no time.
Or if you are good at Perl, you can find one of the many examples
of manipulating $Items that exist.
