I appreciate that you have let us know which theme you are using as that is super helpful! Looking into the options available for theDawn theme, it looks like we can only add images directly to the sectionImage banner. I would suggest, since the the Dawn theme isdesigned and supported by Shopify- you can usefree design time for Shopify themesto allow our internal themes team to make the changes on your behalf.
If you are interested in using thedesign timeto make this change, you will need to login to your store usingContact Us page. This will allow us to securely verify you as the store owner before discussing the changes you would like to see on the online store homepage with a Support Advisor.
