Set the DPI for all exports from the Asset Export window?

Hi,

I'm using Asset Export to export a series of icons as .png files at several different sizes. (image below)

I noticed that the images it exports all have different dpis based on the size. For example, the 200px icon is 7dpi, and the 2000px version is over 500dpi.

I need them all to be 72dpi for web. Is there a way to set the same dpi for all?

Thanks!
