Place constant array into middle of code memory - i.MX RT + MCUXpresso

Question

For testing purposes, I need to split code to two parts to ensure long jumps to flush code cache frequently. Splitting certain object files to sections is not acceptable, as it is deterministic, while production code is not. There's an idea to create large constant array (which I need anyway) and place it somewhere in the middle of code memory. All I found is placing an array before the code or to separate section, but code cannot be placed to both code sections automatically. Is there any solution for this?
