[FEATURE] Sharing python blocks across diferente notes

[EARaceWalker]

I've started using execute code with python and reusing blocks across other blocks using the {pre} tag (eg: a python block that translates an mp4 into a text transcript by using as input an mp4 file in Obsidian ). I wonder if
1 - Is it possible to reuse the main block across different notes?
2 - Can the code to be executed be executed from a button inside other note?
