Custom Sort Codes that automatically cascade - Industry Wide too

Our most used fields that happen to be industry standards at our company is Uniformat and Master format, the main levels used are UF2 & 3 and MF1 & 2 Would love to incorporate both of them into zzTO as a hard coded field and a special cascade field that rolls up, when you puck UF3, it automatically picks UF2 is how Ediphi works.
