spring batch PatternMatchingCompositeTokenizer when there are more than 1 patterns - spring-batch

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,
line3 pattern(with mapper1) exists after a line that starts with ABC and
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
