spring batch PatternMatchingCompositeTokenizer when there are more than 1 patterns

Question

I have a file to read like below. A record is split into multiple lines. Each record can have any number of lines; the only way to recognize a new record is when a line starts with "ABC" and there is another line with identifier ABC_SUB. Each line for this record need to have a separate mapper identified by the pattern with the start of the line(e.g., ABC, line2, line3, line, ABC_SUB, line3, line4) The same pattern line3 and line4 can be present, but they need different mappers based on the previous line type identifier. In this example,

1. line3 pattern(with mapper1) exists after a line that starts with ABC and
2. line3 pattern(with mapper2) exits after a line that starts with ABC_SUB.

How to identify a line3 pattern under ABC vs. a line3 pattern under ABC_SUB?

I tried PatternMatchingCompositeTokenizer, but this gives the first matching mapper.

Is there a way to check a few lines before identifying a subtype(like ABC or ABC_SUB) and giving the respective mapper?

ABCline1goesonforrecord1   //record starts
line2goesonForRecord1      
line3goesonForRecord1       //this requires ABC_line3_mapper    
line4goesonForRecord1
ABC_SUBline1goesonforrecord1  //sub-record where it can have same pattern in below lines
line3goesonForRecord1       //this requires ABC_SUB_line3_mapper  
line4goesonForRecord1
ABCline2goesOnForRecord2  //record 2 begins
line2goesonForRecord2
line3goesonForRecord2
line4goesonForRecord2
line5goesonForRecord2
ABCline2goesOnForRecord3
