Christmas lights controller - memory or fixed mode hack - advice sought

I have a similar problem to others but my circuit board doesn’t look quite like the others I’ve seen solutions for so wondered if you could help me with my specific setup, please?

I have some connectable LEDs (up to 5 strings can be connected with 200 LEDs per string) - 31V -12W

I have the old 8 programmes with no memory problem seen many times before. I can’t see anywhere to add a memory chip as demonstrated by Big Clive and so am somewhat stuck as to what to do (read: COMPLETELY stuck).

I’ve included photographs of my board and power supply and would be most grateful if you can offer a safe solution to either store the last programme selected or just keep the LEDs on static permanently.

Many thanks.
