How can I set up multiple ACH links? To have different payment AR links for various clients?

We have different project accounts for each client. When we invoice, we would like to be able to share a payment link for that client's project account. It seems the only way to do this is to change our deposit account default each time. Can we have multiple accounts so we can create differing payment links at the same time? Basically, wanting to provide a secure ACH link to be paid without sending our banking info in each invoice.
