custom cell type or custom kernel with custom notebook

[sqlreport]

Problem

• when using cell magic extensions, I have to load extension then configure cell magic with parameters on each cell or using config cell magic

Proposed Solution

• I would like to add a new custom cell type for an existing cell magic
• I would like to add a new cell type item on drop down list
• [nice to have] for the custom cell type parameters or config, I would like to use property inspector to configure per cell config by add that cell magic's parameters and values
• [nice to have] for notebook wide config, I would like to add settings editor

Additional context

• example custom extension for custom cell type would be https://github.com/ploomber/jupysql for sql cell type
• example custom kernel that executes scala by default https://github.com/adtech-labs/spylon-kernel
