Include independent reading in personal trainer

I really like personal trainer (PT) but i often need to read some topics that are not necessarily integrated in my scheduled daily readings, especially when i encounter these cases at the hospital, as it fosters a better understanding of the topic. Unfortunately, PT doesn't take that into account, and unless i add the topic to my study block then preview and mark as read the following day, it doesn't integrate it. Moreover, the number of blocks allowed in PT is limited to 6 meaning that if i encounter different pathologies from different systems, i will hit a wall because i won't be able to add anything....
