[EpiData-list] nested RELATES?

I'm using Epidata 3.1 on Windows 7.

Can RELATES be nested? By that I mean, can data entry form A relate one-to-many with data entry form B, and some of the records in B relate one-to-one to data entry forms C?

Specifically, I have a qes/rec/chk setup for households.

within households, there will be several people, each of whose data is entered in qes/rec/chk B

some (not all) of the people will have asthma. For the asthmatics, I want to, conditional on their asthma status, jump to a third qes/rec/chk setup for data on the asthmatics.

Thanks.
