Can the same property value be stored only once in the property table in 3d-tiles

Hi everyone,
I have a lot of features that have the same string property values, and it seems that the same number of strings as the features need to be written to the table whether stored in b3dm’s batchtable or glTF’s EXT_structural_metadata extensions.
Is it possible to store the same property value only once, and all feature’s property refer to this value?
