Have a look at other macro's lots have this construction - it's not
ideal, but it's not a huge problem either.

This is by far the easist way to constructing such macro's, though a
setup like

AS-TELEDK
- AS-TLICUSTOMERS
- AS-TELEDKCUSTOMERS
- others

AS-TLI
- AS-TLICUSTOMERS
- AS-TELEDKCUSTOMERS
- others

would be more clean, but it's not what we've implemented at this time.
