Change configuration for file saving in folder

Question: Where can I configure Vectornator to automatically save my .vectornartor documents in a specified folder?

Device: macOS Big Sur Ver. 11.6
Mac: M1 Chip

Vectornator version: 4.12.0

Due to the Big Sur Vectornator bug that doesn’t allows to automatically save files, I have moved my files to the Library>Containers>Vectornator>Data>Documents>drawings folder and it seems to have worked by now.

I want my future files to keep saving in that specified folder and not in the Documents/Download folder without having to move manually.
