Q: remembering airplay setting

HI,

I have another Apple TV that's rarely turned on downstairs in my house.

So as you mentioned,I do have an "Apple 3" or "Apple 4" option-(which is the one I use).   Since I hardly use

the "Apple 3", is there a way to delete it off my IPad as an option?

Thanks in advance

I did so...only "Apple 4 " shows.  I set it, and after 5 minutes  of non use of the IPad,  it became unchecked and the default "IPad" was checked again.
