Zephyr REST API

I am using Zephyr Test Managment and Automation for Jira Cloud. The REST API to get Test Cycles (https://api.zephyrscale.smartbear.com/v2/testcycles) only supports querying by project and folder according to the documentation.  Is there any other way to find Test Cycles by other parameters, for example, by name or a custom field value?
If the answer is no, are there any plans to improve these REST APIs?
