How can you create half star ratings?

Hi,

I was wondering if there was any possible way to select a half star rating for a product or review item. I have certain items that may fall in the 3.5 or 4.5 out of 5 categories but my only options are to select a whole number rating like 4 or 5.

I would imagine it may not look as genuine if rankings that especially fall between 4 and 5 are always displaying as 5 out of 5 stars. However, I also don’t want to knock the product down a full star to a 4 rating. Please let me know if there is any way to select half star ratings.

Thank you!
