Last iteration of the Search step

How can i identify that the last iteration of the Search step?

On the last iteration, i would like it to stamp a field but I havent found a way to do this through jinja (at least in the way i want it)

this works in getting me the highest record id (which is my default sort for the table):

{% set highest = a|max(attribute="id") %}
{{highest.id}}

and i can use this in the look up step and find the last iteration of the loop, however, i would like to not have to do this part.

on the for each after the Search step, i am trying this:

{% set highest = a|max(attribute="id") %}
{% if a.id == highest.id %}
    {{TRUE}}
{% endif %}

but i just keep getting a TypeError: 'Record' object is not iterable.

does anyone happen to know how to stamp a field in a for each loop only when it is the last iteration of the loop?

Thank you!
