Clue / Handout Sheet with Relationship category

[OWL-Fashioned]

Is your feature request related to a problem? Please describe.
There are quite a lot different single sheet categories, which are linkable via the "relationship" tag, which is awesome. Running Call of Cthulhu there are a lot of Clues / Handouts, which my players come across. It'd be really great, if there'd be a single sheet category for those too (even better if you'd be able to add several pictures or even integrate a PDF-file on there as well). The relationship tab / category is just super helpful for helping me players understand (and remember) all the connections between organisations / persons / locations - and clues.

Describe the solution you'd like
Maybe it'd be easiest (sorry, I have literally no knowledge of coding...) to have a "custom single sheet" category? It'd use the custom category name as lable for the relationship tabs. That would open up your awesome module even more to games like Call of Cthulhu, in which I often create journal entries for (multi-page) clues and artefacts (because hidden text in an item's description is automatically shown to the player, who's checking its description in his inventory...).

Additional context
The module covers already so much, thanks for your awesome work! I guess every system has its special demands for journal entries, like Call of Cthulhu f.e. Therefore a custom single-page option, which is recognized for the relationship tag would be super handy and awesome! Thanks!
