Increase Flash Storage on NEXTION 5" Display

Hi everybody,

I'm currently stuck with a Project. Basically I'm creating a simple software in the Nextion Editor with where you can swtich pages with different buttons.

Unfortunately I have reached the 16 MB flash storage limit and the enhanced 32 MB Version is also not enough.

Is there a way to increase the flash storage. Kinda desperate because I already put a lot of energy into this Project and don't really want to switch systems.

Thanks in advance!
