Boot drive select enhancement?

[Pny]

Since the cartridge is the first thing to be accessed at power on/reset it might (or not?) be possible to implement a true boot selector function in the SidecarT boot firmware? ...making an unmodified Atari, without any hardware soldered boot select switches, boot from external floppy disk drive or other third party floppy emulator such as the Gotek or similar.

Version 0.0.18 will allow custom selection of the virtual drives A: or B:

Ex: Drive A as a physical drive/Gotek, Drive B an emulated drive by the device
