Background
Obsidian currently supports file, header, and block/bullet level link embeds. This is great! 
Some current behavioral details:
- Header level link embeds show all content until either the next header of the same level or the end of the file is reached.
- Block level link embeds show the content of the linked block/bullet.
Use case or problem
Sometimes I want to see header level link behavior for blocks. For example, with a file of this format:
# Heading
- Spec 1
- Detail A
- Detail B
- Detail C
- Spec 2
.
.
.
I might want to embed all the content from Spec 1, but I don’t want it to be rendered as a heading.
Proposed solution
Add the ability to choose the preview/embed style – either just the current line as blocks currently work or the entire “subtree” as headers currently work.
This could potentially be accomplished by adding a single character to specify “full tree”. It could be a double !!, for example: !![[filename#^block_id]].
It would be doubly neat if syntax maintains uniform usage with the behavior of heading links. (So, perhaps reversing the syntax above so the double !! does the single-block embed and single ! does the entire subtree embed as headers do.)
So, in the end, usable syntax might be:
- Entire subtree:
![[filename#^block_subtree]] - Block-only Link:
!![[filename#^block_txt_only]].
I have also requested this behavior for Dendron
