Automatically apply conditional tags to topics according to linked FM file?

Hi, I just started to use Robohelp 2019(.0.12). My target is to generate two versions of an online help with conditional content. The source of this content is a Framemaker document with different conditional tags.

I managed to link the FM file in my RH project and the conditional text is correctly hidden when it should be. The only problem I have is that if a whole section in the FM document is marked to be hidden, the topic created fom that section is still visible in the table of contents of the output. It is empty when you open it, but I would also like to hide the TOC entry.

I achieved this by manually tagging the topic in RH with the correct conditional tag. But can't that be done automatically during the import? After all, the heading from which the topic is generated, is also marked with the conditional tag in FM.

Doing it manually is not a solution for me, because the source document is continuously changing and I would have to do that tagging after each update. I tried. The tags are lost when the linked file is updated in the RH project.

Is this a bug/missing feature in RH 2019 or am I doing something wrong here?

Thanks a lot,

Marco.
