For ISO Direct Debit can we have One Per Customer Receipt Creation Rule?

Receipt Creation Method - Automatic

Receipt Method - Automatic Processing

ISO Direct Debit - Yes

Number of Receipt Rule - One Per Invoice

When we select ISO Direct Debit to Yes automatically the Number of Receipt Rule defaults to One per Invoice and greys out.

Is there an option to have the ISO Direct Debit checked and have the Number of Receipt Rule value as "One Per Customer"?

Thanks for your help.

Kind Regards - kc
