Sdf tags facility

Not sure where to position this post exactly, but it’s related to chemistry.

Is there any way to easily manipulate flags for sdf format molecules within knime. For instance in terms of adding chiral, racemate, and enantiomer, or enantiomer flags, unknown to the molecule. Or for that matter, removing them also.
This is particularly important in molecular data registration.
So far I see no way of doing this. Seems quite a major chemistry omission.
Any planned support from rdkit, indigo, or moe nodes ?
