Ah this is super cool but unfortunately doesn't solve my issue. As the tweens in question woud have different durations...
I might know of a solution for differing durations. I may have something later this week to throw past you if it works out.
Yay, let me know!
I've updated the example project to better adjust for tweens with different timings.
This is not a great solution, as it isn't a streamlined solution, but it might work well enough depending on your needs :)
