Set DO default value based on variable value

Hi everyone,

I have a DO that is sometimes switched during the program execution. It is used for communication with an external PLC.
At controller restart, the value of the DO is reset to its default value, specified In the system parameters topic I/O system - Signal.
I want my DO to be set to the value it was before controller shutdown, and not its default value

I was thinking about setting the DO before program restart based on a PERS variable contained in one of the program module.

Can I do something alike ? Is there any alternative ?
