Is there a way within recursive tables to combine the same item rolled multiple times? For example, I roll on a 10gp Gemstone table 5 times and get 3 Obsidian and 2 Blue Quartz. However the output may be something like Obsidian, Blue Quarts, Obsidian, Blue Quartz, Obsidian. Is there a way to get it to output 3 x Obsidian, 2 x Blue Quartz?
