Need help to break the limit of ped texture slot.

[jerry4726]

What should i do to add more than 26 textures for a drawable component in .ytd file?
I had 26 textures and named them to the final alphabeta character "z"(uppr_diff_000_z_pak), now i need to add 1 more texture (using 27 textures in total). Anyone please tell me which name i should put on it?

Thank in advance.
