Fingerprint similarity node

I have a slight issue/suggestion for upgrade for this extremely useful node.  I really like the inclusion of the possibility to use the Tversky index within the node (especially for pulling out super-structures of a molecule), but when I reset a loop that has the node inside, the configuration of the node is reset to Tanimoto.  Would it be possible to re-configure the node settings to retain the state of the node as saved?
