Selected Atoms get lost in RDkit

Hi,

When taking an SDF, it is possible to highlight one or more atoms within it for manipulation at a future point. (From in-house nodes and MOE nodes (Atom Selector)).

However I notice that if this SDF with selected atoms is converted to RDKit and then back to SDF, the settings for these selected atoms become lost.

Is it possible to have this feature retained through the RDKit nodes. I assume this information is kept in the SDF block, which gets lost during the RDKit conversions.

THanks,

Simon.
