Store code constants in external flash or e2prom

So my problem is that i want to store string constants in an external SPI e2prom or flash memory. The thing is that i want to generate the content (a hex file ) of the memory using Keil if possible. Can someone give me some ideas. Thank you.

I am sure it can be done in th IDE as well, but would not know how since I, for reasons of other builds, do not use it
