This could even be extended further of course, but it's hard to imagine needing more than 8 sets of CL configurations... Just a thought.

YMCPY function from YFNX module can easily backup and/or restore block 1 to 3, block 0 is more tricky but not that much.

Code:

"803>823" YMCPY  // backup block 3 to RAM page 0x823
"827>803" YMCPY  // restore block 3 from RAM page 0x827

I know that these functions operates on a four set of MMU registers, one primary, and three secondary. How I can create a fifth?

Not presently, but you can easily get around the limitation, see above.
I would suggest to use this method for awhile to see if you really need more than what we have presently.
If that is really the case, then Monte could modify the code for sure, the drawback is compatibility with users currently using memory pages that Monte will use.
