Testrail and JIRA subtask interaction

Question

We are using JIRA and have Testrail integration enabled.

Our current implementation does not use "sprint bugs" (subtasks on the stories), but rather only issuetype = bugs.  I've been told this is because Testrail cannot handle subtasks.  I've done some light reading here but I haven't found a definitive answer.  I'd like confirmation that Testrail does not handle subtasks on JIRA stories.

I've found a partial answer.

(Yes, it's overall possible.)

However, the question in the following post makes me wonder if there's a negative impact on Testrail reporting.

So it would still be great if someone more knowledgeable weighed in.
