# Repeat template slides by ID

1. You can repeat a template slide using the slide's unique identifier to create multiple copies as needed.
2. Using `slide_id` ensures the correct slide is referenced even if the slide order or structure changes within the template.

### Finding the ID of a slide:

* Programmatically**:** 
  * using VBA or any library capable of reading PowerPoint XML (e.g., `python-pptx`).
* Manually:
  * Rename the `.pptx` file to `.zip`.
  * Open the ZIP and navigate to `ppt/presentation.xml`.
  * Inside, look for the `<p:sldIdLst>` section, each `<p:sldId>` element has an `id` attribute that represents the slide’s unique ID.
