I don't know if it works with custom tracks but for your local mirror,
check in the README file under trackDb/. You can combine the id and name
you want displayed and have just the id used in the url.
Additional replacement item strings can be:
$T - database table name
$S - chromomosome name (scaffold name on scaffold assemblies)
$[ - chromStart location (zero relative)
$] - chromEnd location
$s - chromomosome name without chr prefix
(or without scaffold_/Scaffold_ on scaffold assemblies)
$D - database name
$P - item name portion before first : in name
$p - item name portion after first : in name up to next colon
