Can't read multiple main headers defined in single copybook

## Background [Optional]
I'm not able to read multiple main headers defined in single copybook .Cause Cobrix can handle only one Main header copybook no multiple.

In my project i have a requirement to read multiple copybooks as One main Copybook using Cobrix.
Example:
TRANSACTION.CPY
01 CUSTOMERS
05 PURCHASES
FIRST_NAME PIC X (04)
LASTNAME_NAME PIC X (04)
01 ORGANIZATION
05 DEPARTMENTS
ORG_NAME PIC X (04)
VENDOR_NAME PIC X (09)
01 MEDICARE
05 BILLS
TREATMENT_TYPE PIC X (04)
LOCATION_NAME PIC X (09)
01 MEMBERSHIP
05 PARTNERS
PARTNER_TYPE PIC X (04)
PARTNER_NAME PIC X (09)

## Question
Does cobrix have a limitation in reading multiple copybook that defined in single copybook? Can we achieve it using cobrix in this case?
