Is there a way to change currency notation on printed checks?

So, I have a few different entities, one of which is Canadian. The Canadian entity often has to write checks to the US entity, reimbursing the US org for payments made on its behalf. Obviously, the Canadian org has a Canadian bank, and accomplishes all of its business in CAD.

We constantly run into problems at our bank branches in the US when we take these checks written in CAD, for deposit into our USD account. The bank tellers are absolutely clueless most of the time and never want to recognize foreign checks, even when we explicitly tell them “this check is written in Canadian dollars, not US dollars.”

What ends up happening is that we'll deposit a check for $1,000 (Canadian), yet the bank always wants to credit the check for $1,000 (US). And then, the Canadian account gets debited for whatever the CAD equivalent of $1,000 USD is. It's obviously incorrect, and makes for a huge mess that could have been avoided if the tellers had just done their jobs. In FE, is there any way I can write checks and label the dollar amount as “CAD” rather than “$” ? At least then, we'd be able to show these tellers that the checks are CAD.
