Xray should be able to do automatic creation of multiple test executions by selecting a number of tests/test sets and selecting environment combinations

Xray should be able to do automatic creation of multiple test executions by selecting a number of tests/test sets and then selecting the environment combinations you want to run.

Client example:
I want to create test executions for 10 tests. I have created test environments for Windows, macOS, Google Chrome and Mozilla Firefox.
I want to test each of those 10 tests in all the possible combinations:

Windows + Google Chrome
Windows + Mozilla Firefox
macOS + Google Chrome
macOS + Mozilla Firefox

Currently, I need to manually create 4 test executions, but I would like to be able to select the combination of environments from the list above and have Xray automatically generate the correct number of test executions for each combination.
