How can I horizontally format or list footnotes/affiliations in a Word document?

I am preparing a manuscript for submission to Nature Cities, and I’m trying to match the journal’s specific affiliation and footnote formatting style.

example
Source: War city profiles drawn from satellite images

In their published articles, the authors’ affiliations are presented in a horizontal list, rather than the standard vertical stacking or block format commonly produced by MS Word.
Current (Standard/Vertical) Output Example:

Affiliation_1
Affiliation_2

Desired (Horizontal) Output Example (like Nature Cities):

Affiliation_1. Affiliation_2

My Goal: I need to know the best way to achieve this horizontal listing for the affiliations/footnotes using Microsoft Word. Is there a specific trick, a Word setting that is designed to change the layout of numbered footnotes or affiliation lists from vertical stacking to a single horizontal line?
