[Feature Request] save option manager for netplay client.

Would it be possible to add an option in the save section where you can select whether the save files are overwritten (as it is now) or not overwritten from the server to the client? This would be very useful for old cores like tgbdual so that the games from the cartridge of player number two can be loaded correctly, because saving the files I have been able to solve it via script, but the loading issue is impossible for me due to the fact that the server overwrites the client files in the .netplay folder. Greetings.

Start by tracing the netplay client's save-section handling and how files are transferred into the .netplay folder. Determine where the server currently overwrites client save files and how an option could select overwrite or preserve behavior. Done means the option is exposed and client files remain intact when preservation is selected, while existing overwrite behavior still works.
