How can I round the corners on multiple InDesign frames?

I am doing a photo collage layout as part of a re-creation of some older creative for a client. I'm rounding the corners in InDesign by clicking the yellow box below the upper-right handle and then dragging the corners to around 5p0. This is exactly what I'm looking for, but I want to know if there is a shortcut to apply the same effect to all 20+ photos?
