LOL. That's insane. Is it one Zelle link, period? Or only to one bank (but you could link several accounts from that one back)?
I believe a single Zelle identity can only be linked to a single bank account, and a Zelle identity consists of an email address, phone number or both. Typically it's the "both" option, but I think that in theory you could create multiple identities with multiple email addresses, and link each to a separate bank account
