Global panels



I contacted support with a feature question but they told me that it doesn’t exist yet, that it is a good idea and that I should post it here in features requests.
So the idea is to have an option to save panel as a global element and then insert it to multiple pages, and then when, for example, the wording or color needs to be changed, it can be changed in one place and all pages with that panel are updated? I am aware that you can save a section as a template and reinsert it on other pages, but I am not able to figure out where to change that template and does the change affects same panels already inserted into different pages.

This feature already exists in some theme, like Divi for example

I hope you will implement something similar since Jupiter theme is our number 1 option for developing our website.
Kind regards,
