Can anyone help me with this;

One of the fields on my form is a CRM field, after I select the SO number from the CRM it will auto fill the account name.

I need to save the last two fields after I click submit record, so I don't have to re-select the same SO again. Doing this, because most of the time I'm using the same SO number to enter multiple records.

CRM field name "Sales Order No." and zoho creator field that will auto fill is "Account Name".
