答案（中文）
如果您是个人注册人，且没有其他公司注册相同物质，则在更新注册时您将不会遇到任何限制。如果相同物质还有其他注册人，则您必须满足某些条件才能更新。您可以在下面找到您的案例场景： 存在针对相同物质和相同注册类型的联合提交，而您的注册不在其中：您无法更新您的档案，直到您加入联合提交。 存在针对相同物质和相同注册类型的联合提交，而您的注册是其中的一部分：只要您不更改注册类型，您就可以不受任何限制地更新您的注册。 对于中间联合提交，仅当尚未为该物质创建完整联合提交，或联合提交之外没有完整注册时，才有可能将您的注册更改为中间和完整或仅完整。同一物质和同一注册类型（完整或中间）不存在联合提交，但其他单独注册已提交：您可以不受限制地更新您的注册，只要您不更改注册类型或直到创建联合提交。对于中间注册，只有在尚未为该物质创建完整联合提交，或除联合提交外没有完整注册的情况下，才可以将注册更改为中间注册和完整注册或仅更改为完整注册。

If you are an individual registrant and no other company has registered the same substance, you will not face any constraints when updating your registration. If there are other registrants for the same substance, you will have to fulfil certain criteria to be able to update. Below you can find the scenarios of your case:
A joint submission exists for the same substance and same registration type and your registration is outside of this: You cannot update your dossier, until you join the joint submission.
A joint submission exists for the same substance and same registration type and your registration is part of it: You can update your registration without any limitation, as long as you are not changing the type of your registration. For intermediate joint submissions, changing your registration to both intermediate and full or only full is only possible if there is no full joint submission already created for the substance, or there are no full registrations outside of a joint submission.
No joint submissions exist for the same substance and for the same registration type (full or intermediate), but other individual registrations have been submitted: You can update your registration without any limitation, as long as you are not changing the type of your registration or until a joint submission is created. For intermediate registrations, changing your registration to both intermediate and full or only full is only possible if there is no full joint submission already created for the substance, or there are no full registrations outside of a joint submission
