Ability to edit in the Query expression viewer

[MarshallRJ]

Is your feature request related to a problem? Please describe.
Recently when configuring a query for a table view filter. I needed to use the in operand instead of the == in the JSON Logic query. The query builder currently does not cater for this.

As a workaround the form configuration was manually edited and PUT with swagger. See the result below

Describe the solution you'd like
The Query builder already has a Query expression viewer. It would be ideal if the was an edit option to allow the raw query to be edited to handle other custom queries (not just the in operand as in my example).

Describe alternatives you've considered
Another option would be to handle the in and some other operands but the edit raw query might still be required for other custom filter scenario's
