LIbrary suggestion - Sources drop down

I have 12 cameras at this time. When going to the library it would be nice to see all of them when I drop down the Source menu. Since selecting this is, the display of the menu is only temporary and it would be nice to see all the cameras there instead of having to drop the menu, scroll down and selecting the one I want.

Some things are predefined in the programming language so have to check if this is possible and/or fits in.
