MailStream Plus - Can a presort be done when some records are LOT (Line-of-Travel) and some are Walk-Sequence (W-S)

Product affected:  MailStream Plus™, all versions, all Platforms
MailStream Plus™ (MSP) does not offer a job to have two types of CRRT sequencing in the same mailing.

These 2 different sequenced records would have to be run in separate MSP jobs sorts. The reason is that ALG CR position 12 has these three main options- 
W File is in Carrier Walk sequence. 
L File is in Line of Travel (LOT) sequence. 
N File is in neither Carrier Walk sequence nor LOT sequence. 

The whole file has to be in either Walk Sequence (W-S), or the whole file in Line-of-Travel (LOT), or neither. 

Note: ALG CR is used in the presort step, and tells the presort step the order the file is in.
It does not matter during the presort step whether the records have W-S numbers, LOT numbers, or neither. Or even if the file is really in the correct order the setting says it is.   
MSP does not validate the CRRT sequence during the presort step. At the time of the presort step, the file needs to be in W-S or LOT, whatever the ALG CR position 12 says it is.
