Anyone interested in improvisation has undoubtedly spent time transcribing ii V7 licks. To get more mileage out of your licks (they dont have to be ii V7 licks) make sure you can resolve each line in more than one way. Resolving a line is arguably more important than what precedes it.
The video example uses a minor ii V7 i progression in Eb minor ( Fm7b5 / Bb7 / Ebm7 / Ebm7 )
In the video I play 2 different ideas (or licks) but I resolve each line to the b7, 5 and b3 of the Ebm7 chord.
Lick #1 Starts with a F dim triad followed by an Eb min/maj arpeggio. Over the Bb7 chord it stays reasonably diatonic to Eb harmonic minor. Then it is resolved in 3 ways.
Lick #2 Starts by using the Abm and Fdim triads. Over the Bb7 chord I use the B diminished scale. Then it is resolved 3 ways.
Working on resolving your licks (especially ii V7’s) is a great way to get more mileage out of material you already have under your fingers. It makes all your licks more useful (because you can resolve them in a variety of ways).
