Expense creator API: associate created expense with card number?

I'm creating an integration for a bank that doesn't support being connected to Expensify (but interestingly they have their own API). I noticed that the Expensify Transaction object includes fields for cardID and cardNumber, but these aren't parameters in the expense creator API. I tried passing them anyway when making the appropriate POST, but they didn't update the card number for the expense (as I expected).
Is there any way to associate an expense with a credit card number when creating an expense using the API? For context, I'd like to create a manual company card upload profile for these credit cards but use the API to associate expenses with these cards instead of uploading CSV files.
