Any ideas for an ideal way to tag particular issues within a trade paperback with a particular reading guide? For example, I have Drax TP Guardian of Galaxy, which collects a number of issues. One of which is Iron man (1968) #55 which is part of Marvel Guide’s Bronze Age 2.2 Avengers vs Defenders. None of the other issues in the TP are part of this reading guide/story arc/whatever you want to call it.
I am afraid I do not see a simple solution for that.
Maybe use a Tag? In the Edit screen, on the Personal tab, you can set Tags.
Then in the main screen of the app, you can use Tag folders to find all issue with the same tag set.
