Unable to borrow Ab-Major in A minor in Hookpad

For some reason, the borrowed chord drop down menu says that it’s a “supermode” chord.

What I need in my song is Ab-???-Eb.

Why is it not supermodal in A Minor?

(On the other hand, the A♭m chord is supermodal in both A Minor and the relative major key.)

To get an Ab major chord in A minor, you have to switch the tab’s key to C major, borrow the bVI chord from minor, then switch the tab back to A minor. It will be listed as supermodal in the drop down menu, because to access it you have to switch to a different mode.

Ah. okay. So that’s how you do it. Thanks!
