go - Regex with replace in Golang

Question

I've used regexp package to replace bellow text

{% macro products_list(products) %}
{% for product in products %}
productsList
{% endfor %}
{% endmacro %}

but I could not replace "products" without replace another words like "products_list" and Golang has no a func like re.ReplaceAllStringSubmatch to do replace with submatch (there's just FindAllStringSubmatch). I've used re.ReplaceAllString to replace "products" with .

{% macro ._list(.) %}
{% for product in . %}
.List
{% endfor %}
{% endmacro %}

It's not sth which I want and I need below result:

{% macro products_list (.) %}
{% for product in . %}
productsList
{% endfor %}
{% endmacro %}
