Hello Julia,

The solution you sent indeed does what I expected.
Although I needed a solution for this specific case, and yours fit my needs
perfectly, I'd love it if you wanted to explain it to me.
Would you mind add a short explanation of this statement:
`position p : script:python(i) { p[0].current_element == i};`
I probably have a simplified understanding of what a position is. Maybe it
is worth digging deeper and having a more concrete knowledge. Any read you
want to suggest to me?

Thank you for your time.
Alessandro
