Re-occurring transfers between banks

I’m wondering if it’s possible to set up a re-occurring transfer between banks, without going through an online bank such as Simplii or Tangerine?

I recently switched my mortgage to HSBC and I’m paying it from a HSBC account but my common law partner uses Scotiabank. Is there a way to set up a re-occurring transfer from Scotiabank to HSBC? We tried contacting Scotiabank to ask but it’s nearly impossible to get through right now.

Right now I have it set up so the money goes Scotia > Simplii > HSBC but would be better if it were direct.

Thanks.
