How to merge a second level array into primary array in TWIG

Is it possible to merge a secondary level array into a primary array without creating new primary arrays.  For example I have a set of “tiles” that need to have an array of “list” that I’m merging like so.

{% set tiles = [] %} {% set list = [] %}

{% for item in content.field_tiles %}

{% if item['#paragraph'].field_image.value %}

{% set tiles = tiles | merge([{

'image': file_url(item['#paragraph'].field_image.entity.uri.value),

'title': item['#paragraph'].field_link_tile.title,

'url': item['#paragraph'].field_link_tile[0].url,

}]) %}

{% endif %} {% endfor %}

I then need to loop through another for loop to populate the list, the below does not work but I think you get the idea of what I want to do.

{% for i in 0..numTagsIndex %}

{% set tiles.list = tiles.list | merge([{

'content': paragraph.field_tiles.entity.field_link_list.entity.field_links[i],

}]) %}

{% endfor %}
