Format presets for linked images and PDFs?

Specs

OS: iPadOS 17.1.2
Obsidian version: 1.4.16 (114)

Intro

Hello, I recently learned how to resize attachments from Embedding files - Obsidian Help, in particular:

  • Images: eg. “![[Engelbart.jpg|100x145]]”
  • PDFs: eg. “![[Document.pdf#height=400]]”

Aim

What I would like though is to have Obsidian save predefined values for images and pdfs, so that when I drag my documents in Obsidian they are automatically resized.

Conclusion

Does anyone know how I could implement this? Is a snippet enough, or will I need a special plugin?
