Export Images with Modified date of Image Capture?

Hi... would love the ability to have the Modified Date of an exported image default to the Original Camera Capture time instead of the date/time of export.... the Created Date can be the current Date/Time but the original date/time should be the modified date/time like LR exports... as of now, I need to run a script post export to change this date or it screws up my DAM program.... thoughts? Thx!
