There are certain data elements that are locked to help guarantee updates are sent to their end destination.
The short answer is no. There are certain data elements for Google and Facebook that we have locked in columns to help guarantee that updates pushed from the live spreadsheets are sent to their end destination (your profiles). The easiest way to identify if something is editable in your live spreadsheet is to view the colors in row 1 of each column.
If the color is a light blue, that means you can write and update and push it to your profiles. If the color in row one is a navy blue, that means it cannot be edited. If you were to click on any column that is labeled with the navy blue color, you will receive this notice.
To complete any changes that you may have made to the light blue columns, press the Update button in the upper right hand section of the page.
