I thought about that, BUT the issue is there is a requirement that I don't share the Company ID like we would be in a select dropdown. We also don't want users accidentally signing up under the wrong company.
I don't understand your reply but what about this:
Form with one Field to check company name (using Seblod validation).
Save button could say 'Search' or whatever
Display Renaming Fields
Now for workflow: Add...
If validation successful, allow user to save form
Using beforestore field grab required data from db.
assign data to relevant $config['storages']['some_table']['some_field'];
When form reloads, it will be in workflow edit, and data will be there.....
That said, you will need the user to click en edit button to continue completing the form, so if your redirect skills are good then you could redirect to edit view after the first time form is saved....
