Avoid slide duplication when only one element change

[95A31]

Hello,
I have several slides describing a process, where the majority of the content is common, and only one image changes. I am wondering if there is a way to avoid duplicating the slides and keep everything clean and compact.

Now I have

---
marp: true
---

## Title
Long text 
Long text 
Long text 
<img src=image1.png">

---

## Title
Long text 
Long text 
Long text 
<img src=image2.png">

I would like something like

---
marp: true
---

## Title
Long text 
Long text 
Long text 

<section data-marpit-alternatives">
    <img src=image1.png" data-marpit-alternative>
    <img src=image2.png" data-marpit-alternative>
</section>

---

Thank you

The build/incremental slide support in Marp is intentionally minimal because that is against the common practice for making better presentations. So there is no specific syntax to avoid duplicated contents currently.

It is necessary to need to make a new Marp (Marpit) plugin to add syntax for generating incremental slides page with duplicated content.

Thank you for the clarification!
