Helpful suggestion re selective blur function

I have just moved to Topaz A4 having given Photoshop up after a long time. I also have On 1 which is good but quirky. So far, I am impressed with Topaz, but have found that I really miss a selective blur function. I do a lot of bird and wildlife photography and deperating the subject from the background often transforms a shot. It the function is there and I’ve missed it.. advice please. The workflow is much better, esp. when multiple shots of birds in flight on motor drive.
Keep up the good work. Tom
