Allow sort titles to be defined or allow sort on alternate title

[dot-mike]

Is your feature request related to a problem? Please describe.
Currently, there is no way to sort on alternative titles. A game may be a part of a series and have alternate titles if such, but I would like to search on alternative titles.

Describe the solution you'd like
Being able to search on alternate titles in Flashpoint Launcher, title is the only field today.

Describe alternatives you've considered
You can narrow down results by developer / publisher and then create a playlist manual, but that requires extra steps and a lot of work.

Additional context
Example:

Addiotional Title   Title
Boxhead 1             Boxhead
Boxhead 2             Boxhead Rooms
Boxhead 3             Boxhead More Rooms
Boxhead 4             Boxhead 2Play
Infectonator 2       Infectonator: World Dominator
Infectonator 3       Infectonator 2
Pandemic I            Pandemic: Extinction of Man
