Hello,
Thanks for reaching out! This is an interesting idea, and I can see how it could be a helpful feature. Unfortunately there is not an out-of-the-box way to schedule an export like this – currently it can only be done manually. If you wanted to schedule an export, you would need to do a customization.
Customizations like this are outside the scope of support that we are able to provide here in the forums, but if you get stuck or have any questions, please let me know. I’ll be happy to see if I can point you in the right direction!
