Taxonomy Manager - Requires reference toggle not available for Table type

When using Document Understanding and configuring my Taxonomy, I would like to be able to choose which fields within a Table require references to the document. This is available for all other Types (ie: Text, Number, Address, etc.) except for Table. This causes friction for the end users where they have to click on something within the document, then manually change the value rather than click on the blue plus sign and type in the value.
