Registration customization and decoupling from login - a module as a new option

-- HikaShop version -- : 4.7.0
-- Joomla version -- : 3.10.11
-- PHP version -- : 7.4

Hi, currently in the definition of the checkout process, when the login module is added as a step, automatically the Hika registration form is added, but many sites (like mine) have custom registration form, for example if a CCK is used (Seblod, Flexicontent and so on) so instead of the Hika registration, the user should be directed to the specific registration form of the site.
Currently this is possible only by overriding the checkout/show_block_login.php but it would be very convenient if there was a configuration option in the login step of the checkout process to select a Joomla module instead of the Hika registration. Since it must work also in a multilingual shop, one option might be to specify the module position (so that multiple modules can be assigned to that position depending on the language) to be used instead of the module id that cannot be a single value.
So in the

show_block_login.php

<?php echo JHtml::_('content.prepare', '{loadposition <position>}'); ?>

Hi Nicolas, yes, the translation key overriding the Hika registration form is a good idea, so that it works in a multilanguage shop. Also the green "Continue" button (together with the form) must be skipped when the override is used.
Thanks! Waiting for seeing it live
cheers
