How to Default Values into Landed Cost Management Trade Operation

I have two client requirements to default values into the Manage Trade Operations task within Landed Cost Management.

1.) The client would like the Currency Conversion Rate Type to default to corporate upon the creation of trade operations (Navigation: Receipt Accounting - Manage Trade Operations - Create Trade Operation from Scratch / Template).

Using the page composer tool in a sandbox I created, I can identify the Currency Conversion Rate Type field; is it possible to default this value to Corporate?

2.) When creating a new trade operation charge line and its associated charge reference, the client would like the Automatically Associate on Match Field to be defaulted with a check mark (Navigation: Receipt Accounting - Manage Trade Operations - Create Trade Operation from Scratch / Template - Create Landed Cost Charges - Charge References).
