Simple Rookie Question: Import then adding logo

I downloaded the "Generic Job Estimate Template" (Excel version) from the Smartsheet website. I understood some functionalities, such as formulas, may not import and would have to be manually input in the cell.

I prepped the Excel sheet with our relevant information in the cells and our logo. Everything came over, except the logo. When I print or email the estimate, the "Smartsheet" logo appears in the upper right corner, instead of my logo.

I cannot find an option withing Smartsheet to edit this. I have a toggle option to have a logo appear or not, but not to edit and replace the logos.

Thanks in advance for any help.
