Video overwrite loop

hey all
this is just a simple request
i needed to manual clean up 278 video’s from my SD card as it was refusing to record timelapses

can you add a function so it automatic overwrite oldest video in case the SD card is getting full ?
ofcourse a option to lock certain video’s could also be fun , so they wont be overwritten

but it bugs me a lot that when i do not manual clean up that i lose my timelapses ( in this case a 17 hour color print … )

Thank you
