Calling "blocks templates" or "block groups" in an object

Is your feature request related to a problem? Please describe.
Sometimes, a user will want to reproduce a particular bloc structure that they often use in repetition through several different object.

For example, if they use the Cornell Note Taking system, they might want to use a “Cornel note” object type; but inside this object type, they might want to quickly add a new line with a “cue” text block on the left, and a “note” section on its right, with always the same width for both.

Currently, if one has to do such a thing, they have to copy/past existing blocks, that might be filled with text; or to always leave out an empty set of block to be copy/pasted.

Describe the solution you’d like
Ideally, it should be possible to create something like “inline templates”, or “block groups”, or “block groups templates”. These could have a name, and could be called with /.


Making it available in the / menu is great but the templates should be limited to the type for which it is created so as not to clutter the / menu for other types without the templates.

I can definitely understand the flexibility of this request but this seems like a great candidate for a plugin since templates can be used for most of the use case for majority of users
