Ability to copy text from multiple panes simultaneously

Use case or problem

When copying and pasting text, sometimes I would like to do so with lines of text across multiple notes.

Proposed solution

It would be nice to able to ctrl select text across multiple notes in adjacent panes and have the copy function copy all of the selected content.

Current workaround (optional)

I just select and copy the text sequentially, letting it store in a clipboard manager. Then I can use a macro that triggers the keyboard shortcuts set to paste the saved content for the past couple clipboard manager storages.

The problem is that I have to have different macros depending on how many items I am copying.
