Hello Agus,
If you are able to filter the adjustment Transaction in a single row (or column) via the row modifier then you can do the following:
1) Create a line that filters on your adjustments by referring to the adjustment journals
2) Add a second line that only filters on your account
3) Create a calculation row that deducts 1) from 2)
If you like then you can define the first two rows as non-printing rows.
This should work.
All the best,
Ludwig
