User-friendly method or macro library for data transformations?

Hi all,

I'm looking for a user-friendly way to make a method library available in DTL, and by user-friendly I mean via '..MyMethod()' or '$$$MyMacro()' rather than  '##class(MyPackage.MyClassName).MyMethod()'.

Does anybody know of a way to add a second superclass or a set of macros to a DTL ... or some other trick?

Cheers,

Otto
