Change export folder for highlights

Hi

I am using the latest version of Koreader on Android 13 which is running on Boox Note Air 4C.

I note that there is a option to change the export folder for highlights; however, that this has to be done for every export, and the folder you set does not stay as the folder for every subsequent export. Is there a way to set a custom folder that is used for all subsequent exports?

Thank you.
