MSPM0-SDK: How to debug project with offset flash

Part Number: MSPM0-SDK
Other Parts Discussed in Thread: CCSTUDIO

I want to have two firmwares loaded into the device. A boot and an app. Let's say the boot fw has a blinking green led and app fw has a blinking red led. Loading and debuging boot fw is straightforward as all I did was limit the flash size for the fw in custom device_linker.cmd file. I am having issues with debugging the app fw. Flash start has offset of 0x1000 . In SECTIONS the .intvecs: > 0x00001000. Next would be to setup a "run command" as SP = 0x00001000 and PC = 0x00001004 but I can't find any information about this in documentation how to set it up, so that the debug would work. Could you point me to the right direction? 
PS: I am new to CCStudio and TI MCU.
