Modifying migration objects is still a little bit more restrictive in Public Cloud scenarios when compared to their onPremise / private cloud counterparts.

From a pure data migration point of view, there are basically 2 options when it comes to extending existing migration objects:

1. Consult SAP note 2999428. Here it is possible to find migration objects for which some additional fields are already available can be synced to the relevant MO.
   2999428 - Collective Note for extensions via Model Your Migration Objects - Migration Object Modeler App in SAP S/4HANA Cloud, public edition (Migrate Data Using Staging Tables)
   
   
2. If the desired object (or field) is not in the list, the remaining approach is to submit a feature request, where it will be possible to lay out the business case for that particular implementation:

One additional path that can be pursued has to do with "in-App extensibility" / "key-user extensibility". This is a more modern way of seeking customization of applications which, in turn, can reflect on the fields present in the respective migration XML template. More details in the following document:
