Prima Luna EVO integrated - input reset question

I’ve recently purchased an EVO 200 integrated.  It’s got 5 inputs, including a Home Theater bypass input.  BUT, when you turn it on, the input selection resets to Input 1 every time!  This is a bit ridiculous, though I do understand why.  The cost of adding some "memory" electronics would raise the price.

What I really want is to use the HT bypass as my normal "everyday" input.  But I cannot do this.  My AV PrePro turns everything on, and I need the system to just power up and work without manually futzing with the amp input.  For now I simply use Input 1, but I’d really prefer to use the HT bypass.

Does anyone know if there’s a DIY mod to change the default input selection??
