Swiss accounting users can now enter a separate ISR reference for bank accounts instead of relying only on the account number. This helps businesses work with banks, such as UBS, whose payment references do not follow the standard account-number calculation.

[IMP] l10n_ch: allow setting a value different from the account number for the ISR reference of the account. Indeed, some banks (for example UBS) use ISR references that cannot be computed from the account number.

The inter-company rules settings have been redesigned to be easier for users to understand and configure. The new setup guides users through the choices in a more natural way, reducing confusion during onboarding and day-to-day configuration.
