Cannot auto-detect because that information isn't available. Free code space is a property of the game itself; it can't be reliably inferred from the cheats — at best, it's just a guess, and never 100% accurate.
You can check it manually with Breeze: open the Bookmark menu and add MiscPointers. Then toggle Absolute Address to see where it starts. Set the last three digits to FFF to estimate the end. Note: if you've activated any ASM cheats, this will no longer be accurate.
I have added the screen for assemble gui. If you have python you can already use it. Since it is so minor I won't make a release just for it.
