Run a single django test

I'm a new PyCharm user, but I've found the run single unittest command invaluable in Intellij.
However, it doesn't seem to work for a single django test when the test file isn't in tests.py.

For example, if I'm in a test method in class TestX in file:
modname.test_classname.py

And right click Run-> Test:modname.tests....

It creates a test configuration with target

modname.tests.TestX.test_method

rather than

modname.test_classname.TestX.test_method

Any way of it supporting the actual test file?
