Changing coolors in Buzz Bulk Create

Has anyone found a way to have a color variable for bulk create in Figma Buzz? For example, I have an ad. I want to make 5 variations with different background images. I also want each ad to have a different font and button color. Do we think there will be an update down the road to make these edits in the google sheet for bulk create or will it need to be done manually after creation? Am I missing something? Thanks!
