Create List and Array Data Types that uses a PPG and not memory

When working with large arrays or lists, like with a Complex Record Map, and you get files with 200 000 lines, it uses a lot of Per Process Memory. Sometimes the process might even run out of memory if the file is too large.

Can ArrayOfX and ListOfX datatypes be created that store the values in an underlying Process Private Global? This will take a load off of the memory. The option should then also be available to use this on Complex Record Maps.

As a side note: Cleanup on destruction of variables of these types will be very important.
