The Suntech Universal protocol has a feature ("assignable headers", read sections 2, 19, 20, 21 of Universal Reporting Guide 1.185) in which you can append custom free-form ASCII fields at the end of the report for things such as external sensors. Traccar, however, does not implement support for such fields, ignoring them completely. This means that they do not appear anywhere in the position attributes object, making them impossible to read from a computed attribute.
Ideally, Traccar should parse those fields (based on ASSIGN_MAP) and store them somewhere in the position attributes, so that computer attributes can be configured to read from those headers.
If this a feature request, it should be on GitHub. Don't forget to provide some samples.
