What button enables the insertion of additional locations in an assemblage data record?

The choice that allows for the insertion of additional locations in an assemblage data record is the option that corresponds to adding or making modifications within the record structure. When managing assemblage data, the function primarily aimed at including new information, such as locations, would be to make an addition to the existing dataset.

The function of splitting is generally used to divide a record into multiple parts or to separate components of an assemblage, not to insert additional locations. This ensures that the integrity of individual items remains intact while allowing a clear delineation of different parts.

Therefore, the correct action that signifies expanding the data contained within a record by including new locations aligns with the primary goal of enhancement and augmentation of the existing dataset rather than division or combination.
