Can we in Oracle Fusion customize the load of BAI2 file?

Summary: In EBS R12 we have a custom BAI2 templates and want to reproduce this in Oracle Fusion.

Content (please ensure you mask any confidential information):

Example type line 88 content some value delimitate by "," and when it load in Oracle Fusion those are all put in different field.

We have rules based on multiple value in this type of line, in R12 we put all informaiton of line type 88 to one value. So the rules apply on all information in this value.

Example: what I put in Black and Italic in R12 is in one value but in Oracle Fusion is 4 different value.
