How can I add an article to several collections?

Hello everyone!

Had been a little confused while creating articles and collections for my students.

We've got 2 collections like "Methodology helper" and "Assessments", where I want to put the same articles about the process and meaning of assessments. But as I see it, Intercom doesn't allow adding one article to more than one section.

And the possible solution of creating two of the same articles just to put them in different collections looks kind of strange to me, as we can't get the right statistics of the use of this material.

Does anyone know any ways to fix it?

Thank you in advance!
