There are many ways!
Quite stereotypical is using any tone as dim7/V to I46-V-I. With this we can go directly from Ab to G#dim7 (=vii°7 of A) instead of A you take A46 - A7 - D. (Note that the V46 chord is the same as the 2nd inversion of the tonic.)
But with this trick you can try any other way like e.g.
Tonization of Ab: Ab-Fm-Ddim7-Eb46-Eb7-Ab
