I think only by changing the source code for now. Perhaps at some point I do a new build, but there is not much people using the app for now.
I really hope you do that someday. I use Motion Vector exports to create animations for personal projects with a super interesting and visually attractive result!! It's an amazing software!
But if you don't want to, I really understand your decision and will try to adjuste it myself (with no idea of coding😅😅)
