I'm in a situation where I need to batch save/import a bunch of values for a profile2 entity. I have a computed field that works for a user registering manually (submitting the registration form), but in this batch/programmatic case I need to set the value for all the fields - including a computed field - programmatically (outside of computed_field code). I'm currently using Migrate Extras, but I think my problem - that the computed field code runs last before saving to the DB - needs to be solved by temporarily changing the computed_field code while I run the batch.
I'm wondering what I could put in the code field, e.g.:
$entity_field[0]['value'] = [the value that migrate extras process has set & wants to commit to the DB]

Advice?
