There needs to be a way to use an existing crosswalk so that unique IDs can be linked across discrete files. Right now, a crosswalk per file is created, which means that observations cannot be linked across files without combining multiple crosswalks together.
Example case
The example case is in panel data, where each file represents a unique time period, but individuals will be observed in more than one period.
