Yes, if you have tablefile from single.bin. In the PurpleCatTool folder is a table of the original disks. For mod disks need a new table.

There will be no conflict. Just this procedure should be done for each disk separately

Is it easy to make a table file? Can i just look at the locations in an unmodded version? In a hex editor? Compare. Then change accordingly? btw, i don't have any free time to attempt this till friday... my day off from work!

--- Quote ---TOC
The Table of Contents (hereafter TOC) is literally the most important file to work with for purposes of Chrono Cross modification. It is essentially a giant pointer table that the game engine uses to determine where every file begins and ends, and occupies 12 sectors beginning at sector 24 (offset 0xc000 in an ISO, offset 0xdcc8 in a BIN).
The TOC entries have a four byte stride and can be presented thus:
SS SS FS BB
Where...
S = "Logical Sector"; 2.5-byte little-endian pointer indicating the sector boundary on which the file begins.
F = "Flag"; the first bit of this nybble will be set if and only if this TOC entry is a duplicate of the next real record.
BB = Number of zeroed buffer bytes between the end of the file and the next sector boundary, divided by 8.
For instance, the entry for file 0001 is 4E 01 00 F7. To find the starting location of this file in a CD image, we first reverse the first 2.5 bytes (yielding 0x0014e) then multiply the result by 2048 for an ISO image (= 0xa7000) or by 2354 for a BIN (= 0xbff3c, then add an additional 24 to account for the sector header, giving a final total of 0xbff54).
