Bootmod3 map questions

I got the Stage 1 multi-map as the included BM3 map, and got to wondering how I could make a custom multi-map.

Ideally, I would like a map that is arranged as follows;
1. Stock 435i map
2. Stage 1 91 Octane
3. Stage 2 91 Octane
4. Valet mode

I'm tech savvy, a network engineer, and no stranger to command line programming., so I'd love to try this myself. However, I don't know what programs are used when creating these maps, so it may already be out of my scope.

Aside from that, my car used to cold-start and hover the RPM's around 1400 for about 10 seconds, then slow down.
I've set cold start and cat pre-heat as OEM on the multi-map, but it still doesn't seem to be doing that. GTS startup roar never seemed to have worked either.
