Is there a plugin that anable dynamic hierarchy inside a note?

for example:
in my course we study from presentation, and there are multiple lectures on one powerpoint presentation.
the basic hierarchy is by lecture. but i want to be able to change the hierarchy leveling dynamically and to have the presentation as first level with relatively short action and to be able to reverse the order later.

is it possible to create a way for Obsidian to understand that it belongs to the same group (for the change to be right)?
(all the the presantation with the name “x” is under the same heading in the new hierarchy)
