Adding a custom form to the admin to edit a custom section

Hi I am new to Shopify,

I work for a school. And right now I am exploring adding a section into our shopify store that displays a bio of instructors in some of our products. I am able to do this in the code no problem. However I would like to add a section in the admin for people in our marketing department to edit this section without going into the code. Is this possible?

Maybe add some global theme settings to capture this information (if you don’t have a ton of instructors). Then it can be captured in the admin. The Shopify admin is not editable, so you can’t just add a new page for custom content management purposes. I guess that’s what theme settings are for.
