There are 2 scenarios for which this would be useful

• I own the same title on multiple platforms. This happens a lot with all the giveaways on various platforms. It would be nice if I could merge the duplicates together into a single title, and then have the ability to install or launch it from the platform of my choice.

• Titles for there are multiple episodes. For example, the TellTale Back to the Future game has 5 different episodes, which each appear as a separate entry. Would be cool if I could collapse all of those into a single title and choose which episode I wanted from the detail pane.

For now, I've been just hiding the duplicates and subsequent episodes after the first. It's an ok solution, but merging would be really nice to have.
