Hi,
We have an anonymous access multi step form that has three steps -
The first step is allows the user to create a record in the Accounts table -

On clicking Next, they enter the Focal Point details which then creates the Contact table record -

In the multi step form configuration, we have set the Associated Table Reference on the second step and hence when the contact record is created, the Parent Customer Id field is populated. This works as expected.


Now, the third step is an event registration step -

This table in the last step has Lookup columns to both the Account table and to the Contact table ("Registrant" field) as shown below -

We are able to populate the Account ID column of this table using the same Associated Table Reference concept -

But, we also want to populate the Registrant with the contact Id from the second step. But, since the setup only seems to allow a single "Associated Table Reference" config, we are unable to populate the Registrant field.
First question is why the Associated Table Reference is constrained to only one entry.
Second question is, how can we get access to the record id of the contact record created in the second step in the third step. If we can get the Contact Id value, at least we can use custom js to update the value in the Registrant field.

Thanks
