Gorm Create special index for postgresql's jsonb via grom.

For index on postgresql's jsonb column, it there anyway to create below indices, via golang struct's tag:

• CREATE INDEX ON quiz USING gin (questions jsonb_path_ops); This is a gin index, specify a non-default operator class.
• CREATE INDEX ON quiz_run (((valuation ->> 'percent')::float)); This is a b-tree index, apply on a sub field of a jsonb column.

Currently I have to create them by hand.

Wondering what's the best way to create these indices if gorm is used?
