Call Custom Queries, programmatically, with variable parameters

If connecting to the PeopleHR API programmatically (through say bespoke software) it is sometimes necessary to access custom queires as well as the standard set of funcitons.

However, if the query is designed with one or more filter criteria, this criteria is not accessible via a programmatic API call (as parameters), only the main Query name with whatever static filters it was last saved with.

If I wanted to have a custom query that could be run against a specific EmployeeId for example, where I would change that ID when running the query in the PeopleHR interface, I'd also like to be able to pass this programmatically like I can with the standard API calls (GetEmployeeDetailById for example, which has a parameter called EmployeeId).

I was surprised to find this was not a standard feature of being able to access custom Query via an API call, and would certainly make a very powerful (and useful) addition.
