Selecting a map feature to collect data about

20 previously collected locations of households (and some additional identifying data such as the head of household name) to visit and conduct a long survey. the survey needs to access the selected household identifier and attributes to confirm at the right place and link the data later in analysis. the initial survey to locate the households and the 2nd more detailed survey are different forms and have a methodology/process step in between that is external to ODK Collect/Central.

This sounds very much like a longitudinal survey usecase: the first 'survey' captures the essential entity household (aka 'entity') data - eg location, household name, etc - and the 2nd, or subsequent, surveys capture further additional or followup data. Where the original captured location of the entity is used to direct the surveyor where to return.
