Customer contact Entry - Open with context menu

Good Morning,

I want to use open with from customer contact field on sales order per below and open my updateable dashboard and pass the customer ID and ship to ID to the dashboard. The open with works… just can’t figure out how to pass IDs.
With IDs, when user does new record I will default the IDs to get filled out. This is all to bypass the silly (IMHO) security on customer contact entry where users need full customer entry privileges to enter contacts.

Does anyone have any suggestions? I’m at wits end with trying via BPMs.
