Need more query parameters on Zephyr REST API

When can we expect the Zephyr REST API to be updated with additional query parameters? At the moment it only supports four, which is far too limited for practical use. Specifically, we need the ability to query by custom fields and labels. Right now, we’re forced to pull all available data and then filter it ourselves, which is both inefficient and significantly impacts response times. A more scalable approach would be to allow direct queries for the specific items we need, reducing unnecessary overhead and making the API far more usable at scale. I can see that there are (Next Gen) versions coming but they lack the query parameters that day to day users actually need to be efficient. Please fix this.
