How do i set up the direct debit if I need two signatures?

Hello Capelcckent-gmai, 

Welcome to the Community page, 

Is this for GoCardless or your subscription payments? 

If it is for GoCardless, it is not supported, you may be able to set it up with GoCardless  direct. Here is an article that has more information to take a look at. 

If it is for your subscription you need to send in this form here.
