You can define your own value formatter with 
TBaseDebugManagerIntf.RegisterValueFormatter

But: it works on a type-basis and not variable name basis. So define a 
specific type euVector:

   TeuVector = type Integer; // or type whatever

and then register it with RegisterValueFormatter(skSimple, 'TeuVector', 
@MyFormatFunction);

See how TDateTime is handled in ide/debugmanager.pas
