Oh no! Football damage!

It's a full-time job maintaning this garden what with pests of all kinds including the son who has accidentally broken several branches off my dwarf azaelea.
I only planted it a couple of years ago and it was doing so well!
It will survive....there are a couple of branches left but I wondered if there was any way I could use the 2 snapped branches to propagate more? There are new shoots on them and when I put them in water they perked up.
Any ideas anyone, please, pretty please.....?

Do I plant the old wood whole branch (about 8") and how deep/ what prep or should I cut off some of the (rather small) shoots?
I remember seeing someone somewhere (Monty?) doing softwood cuttings and making sure there was a "heel" of the old wood?
Probably completely the wrong time of year for this too!
