Saving a set of WiFi details to be run on boot

Hi there, I have a setup with a ESP8266 board connected to the WS2812 LED strip running on WLED but everytime I wish to update the WiFi preferences (Network name and Password) when attempting to conenct to a new network, I have to connect to the “WLED-AP” network before changing the WiFi preferences to the new network.

Is there a way for me to enter the details of all the potential networks I wish to connect to and have the ESP8266 run the code on boot and attempt to connect to any of the network I’ve entered in order?

No, unless you change the source code.
