Add Ability to include query parameters

Currently the default query for Import All is "*"

In TRIM, you can drill this down, such as "login:*" to get all users with a populated login attribute.

Would it be possible to add the ability to fill in a query string on the connector page, which - when filled, would override the "*" sent to the endpoint? 

I've tested this with the REST v8 and confirmed it works. Personally I need this for v4.1 but can see it being useful for newer connectors also.
