Batch change to graphics resolution in many .fm files

Hi, all.

I have imported ~100 .html files into Structured FrameMaker 2015. These files contain ~300 graphic images, total, which FM imported at 72 dpi. I would like to convert them all to 110 dpi. Is there a way to do it through one batch process? (If it requires a plug-in, I'm all for it.)

Thanks.
