Externalization with Asymptote

There is a way to externalize pictures with Latex. I’ve created a folder qwe in the directory where my main document.tex sits and typed:

documentclass[a4paper]{article}
usepackage[utf8]{inputenc}
usepackage[T1]{fontenc}
usepackage{tikz}
usetikzlibrary{quotes,angles}
usetikzlibrary{external}
tikzexternalize[prefix=qwe/]
begin{document}
    begin{tikzpicture}
    draw
    (3,-1) coordinate (a) node[right] {a}
    -- (0,0) coordinate (b) node[left] {b}
    -- (2,2) coordinate (c) node[above right] {c}
    pic["$alpha$", draw=red, <->, angle eccentricity=1.2, angle radius=1cm]
    {angle=a--b--c};
    end{tikzpicture}
end{document}

Works like a charm! Although, I create Asymptote pictures.

Is there any analog to externalize TikZ library but for Asymptote? And how to use it?

(I have ~300 pictures in Asymptote and want to save time waiting until they all are being compiled. I bumped into externalzie option when I have the same problem with TikZ)
