MSP430F6779A: Can we select multiple address execute code in by bootloader

Part Number: MSP430F6779A

Tool/software:

We would like to have application to select execute code with multiple address execute code.

e.g. if we have MCU msp4306779A with 512 kbytes but split 2 areas (each one
256 kbytes). #1 Code and #2 Code. we can select multiple address execute code by bootloader right?

I think it related to this application noted "Creating a Custom Flash-Based Bootloader (BSL)" SLAA450G

Could you please advice,
many thank.
