How to display bus route name in PT line window?

Dear all,

As you known, once the PT line file (xxxxxx.lin) is opened in Cube, we can post lots of PT line attribute variables, such as headways, modes ( via Layer control->Lay properties->Transit Layer Parameters ->Link Posting as shown in the attached PrtScn).

Like other PT line attributes , the bus route names, such as 102i or 102o, are defined in the PT line file, but they can not be posted in the window. Anybody can help?

Many thanks

Yun
