Append text to a pivot table column

but I'm also doing a pivot table where these number values are getting added (Sum). I just wanted to check if there was a way to append the text "Hrs" in the pivot table where the number values are shown without affecting the calculation?

That works great, thank you!

Just one doubt, I have some values with decimals and some without. Can I extend it to include ##.#" hrs" along with ##" hrs" ?
