Is there tab for DAD?

I usually play in DAD,  had a new student,  tuned her dulcimer to DAD.  Gave her a packet of one line tab.  Worked fine.  But she has neuropathy in her hand from cancer,  so she wants to stick with droner style playing.   There is a limit to the tab I have in DAD for only one line.   Should I have started her in DAA ?    Is there tab available somewhere for noter playing in DAD?
