User Defiined Functions using Mathcad?

I have a set of user-defined functions that I use regularly, and I don't want to go the trouble of pasting them in the top of my mathcad sheet each time, or creating/linking a new DLL. Is there a way to create user defined functions using Mathcad? Is there any easier way that to paste them in my worksheet each time?

Thanks,
