Cannot make the templates load from a subfolder

Describe the bug It seems that loading a template from a folder relative to the presentation file does not work (Or maybe I do not know how to make it work?)

Samples to Reproduce

Presentation file:

---
title: Failed template load
theme: consult
---

<!-- slide template="[[templates.slides.def.splash]]" -->

## Works!

---

<!-- slide template="[[templates/slides/def/splash]]" -->

## Does not Work!

Template:

<grid drag="100 100" drop="top" style="background: radial-gradient(#F6F8FA, #808080);">

<% content %>

</grid>

The template file is saved twice, with the same contents in two different locations:

Once with the name templates.slides.def.splash.md in the same folder as my presentation (which "proves" that I can load templates that are in the same directory as the presenation.
Another copy at templates/slides/def/splash.md (which "proves" that I cannot load templates from a relative path)

Expected behavior

I would expect both slides to load the template.

The goal here is to be able to reuse the same set of templates across multiple presentations, but without having the templates "polluting" the folder that contains the presentations. Maybe even be able to switch templates by using templates/slides/[theme-name/splash or something similar.

Thanks!
