Separating groups with different segments

I am trying to parse 820. Some of them have ADX before the RMR (According to the TP reference, this ADX loop contains adjustment items which are not netted to an RMR segment in this transaction set) while some of the ADX are part of the RMR (This ADX loop can only contain adjustment for the immediately preceding RMR segment and affects the amount RMR04. If this adjustment amount is not netted to the immediately preceding RMR, use the outer ADX loop (position 080).

I am unable to extract and separate the ADX. If I follow the code below, it combines the ADX. I want to list out:

1. ADX (not related to RMR) and their REFS
2. RMR and their REFS
3. ADX related to their preceding RMR and their REFS

```csharp
[EdiMessage]
public class RemittanceDocument
{
#region Header Trailer

[EdiValue("X(3)", Path = "ST/0", Description = "ST01 - Transaction set ID code")]
public string TransactionSetCode { get; set; }

[EdiValue("X(9)", Path = "ST/1", Description = "ST02 - Transaction set control number")]
public string TransactionSetControlNumber { get; set; }

[EdiValue(Path = "SE/0", Description = "SE01 - Number of included segments")]
public int SegmentsCouts { get; set; }

[EdiValue("X(9)", Path = "SE/1", Description = "SE02 - Transaction set control number (same as ST02)")]
public string TrailerTransactionSetControlNumber { get; set; }

#endregion
public List Adjustments { get; set; }

}

[EdiSegmentGroup("ADX")]
public class ADX
{
}
```

Start with the RemittanceDocument and ADX declarations shown in the issue, then trace how EDI.Net maps repeated ADX, RMR, and REF segments into groups. Use the two sample 820 transactions as parsing inputs. Done means non-RMR ADX segments, RMR segments with their REFs, and ADX segments associated with the preceding RMR can be distinguished without combining unrelated adjustments.
