How to put footnotes in a separate text box in the sidebar in InDesign?

Hi there! Wondering if there is an inherent way to insert footnotes but have them display in separate text boxes instead of at the bottom of the page. Basically, I'm trying to create this layout, but where there are asterisks there would be numbered footnotes. This would be much easier to manage than manually inserting numbers/asterisks every time: 

(I did see a similar question while searching the forum, but it was from several years ago and required a script download, and I don't want to download anything. Just thought I'd check if there have been any updates since that would allow this.)

Thank you!
