user defined parameters allowed address range on chevy/gm P59 with OS 12592618

I'm trying to decide whether or not to purchase the "User Defined Parameters" feature, but it will be useless to me if the allowed address range does not include the area I need to change.

What is the allowed address range on a chevy/gm P59 with OS 12592618?

I attached my hpt file, so if anyone who already has the feature could check the allowed address range and reply with it or a screenshot, I would be very grateful for your help!

If the address range is not allowed, then I'll have to do some monkey business every time I write with hptuners to re-read the bin in another program, make my changes in hex editor and re-write, knowing that I'll be causing a checksum DTC to be thrown. Not fun, but it would be one way around the problem.

Here are the allowed address ranges.

008030 - 015FEF, (00DFC0)
016020 - 01912F, (003110)
019160 - 01D3AF, (004250)
01D3E0 - 01DCAF, (0008D0)
01DCE0 - 01F6AF, (0019D0)
01F6E0 - 01FF9F, (0008C0)
01FFD0 - 01FFEF, (000020)
