Philippians search abbreviation

[Troy]

In the verse search window, "phm" finds Philemon, but "php" yields nothing. You have to search "phil" for Philippians, even though those are the same first four letters in Philemon. It's a lot easier to distinguish between the two books in my own notes and when sharing with others by using "Php" and "Phm." So my request is to add "php" into the search vocabulary to come up with verse results in Philippians. Thanks!
