wanted: randomization in endnote

We use EndNote often for scientific projects. In science randomization is often required.

If we work with large quantities of references that need to be reviewed we want to split them randomly between multiple reviewers.

I would like EndNote to be able to sort references randomly!

Now i usually do some variations of seamingly random sorting on non descriptive fields (for instance page number, volume etc). but this is not rendom enough, and very time consuming.

I have seen other people do the same, and would like to be able to tell endnote: select 500 random references from this group.
