Preload .csv file in ODK Aggregate to call existing fields

Greetings group, how could we store data from a form to a .csv with data preloaded for it ?. We use a VM as an ODK Aggregate server. We take an example of the official documentation of the following address, but nevertheless it does not work. http://xlsform.org/#pre-loading-csv-data

thanks for your help

What specifically do you mean by "it does not work".

  1. What steps can we take to reproduce the problem?
  2. What you have you tried to fix the problem?
  3. If you have a test form or screenshots or logs, please attach.

First, what I need to achieve is to include data entered through other forms to another form created, making a query of them from the other form to replicate the error. In ODK COLLECT is it possible to add records entered into other forms to a select field ?.
