Using mol_adjust_query_properties()

[adam-of-barot]

I recently needed to do substructure queries that take into account explicit hydrogens. I found out that the mol_adjust_query_properties() cartridge function does what I want.

I gathered that there is no built-in way to access that feature through field lookups.
I managed to do it by creating a new Lookup and registering it to MolField.

Is there be a cleaner way to do this? My solution also doesn't support additional parameters unfortunately.
