Can I add a ppa to a custom sources.list?

Question

Is there any way to add a ppa to a specific sources.list?
add-apt-repository by default adds new ppa to /etc/sources.list, I want to add a ppa to mysources.list

Answer 1

You can add it to mysources.list so long as you put that file in /etc/apt/sources.list.d.

You can read more about how apt searches for sources with man sources.list.
