Getting Intellij to pick up Freemarker macros

I'm trying to get intellij to properly pick up freemarker macros defined in includes.

If I create a file base.ftl that has:

[#macro test name]

Hello ${name}

[/#macro]

And another file index.ftl:

[#include "/base.ftl" /]

[@test name="John" /]

Intellij doesn't complain about finding base.ftl, but it complains it can't resolve the macro test.

Any way to fix this?

Thanks.
