Can you get a Fender flatwound B string as a single?

[miles'tone]

Hi all.
I'm a out to string my fretless J-bass BEAD and just need the .125 B string as I already have Fender flats on it.
Tried searching and some stores say you can but they don't stock them yet I haven't seen them online as singles (been offered almost every other brand though)

Anyone come across them as singles?

(Oh, yes I have tried Fender and of course had no reply )

At this time they do not sell single bass strings.

But I am sure there are some companies you can talk to and they can work with you on removing a string and re-selling an open 4 string set as an open item
