[FEATURE] Define target for Persistent Output

[jedifindtrick]

Is your feature request related to a problem? Please describe.
How persistent output is working right now with outputting it directly below the code block, there must be three empty lines after it to not break/replace anything that comes after.
So if you have multiple code blocks it can quickly get messy if you don't want it to break things.

For example, if I were to run the following:

Before:

After:

And the same thing is if you run it multiple times but have the "proper" spacing:

Before:

Run 1:

Run 2:

Run 3:

Describe the solution you'd like
The way I see it, some possible solutions could be:

• Have it output to a predefined property in the note (would be nice).
• Have it output to another code block that contains a specific string (similar to using sed to replace something in a file).
• Automatically add a certain amount of line breaks to the output as to not break/replace other content in the note.
• Have it work similarly to the QuickAdd plugin where you can specify specific headers that it should be output to and also if it should append it to the top/bottom of the file/header (simlar to using echo "Text to append" >> file.txt and sed -i '1i Text to prepend' file.txt).

Describe alternatives you've considered
Short of not using persistent output, nothing I've tried has worked (due to what was explained above)
