STM32F4 extending the heap to seperate RAM regions

Hello everyone,
we got a project where we need literally any space available for dynamic heap allocation.
So we now switched from a F2 to a F4 setup, because it has more RAM. We are using the STM32F427 at the moment. As I learned now the RAM doesn't just get bigger but now has seperate RAM regions, which are organized by KEIL via IRAM1 and IRAM2 sections (192kB and 64kB).
So now my question, is it possible to really use every bit of free space for the heap management, basically splitting it up into the remaining IRAM1 and all of IRAM2?
Any help is apreciated!
