Mixed text formatting in one cell

I am using CONCAT to assemble academic citations - basically just joining together a number of text cells, ending up with another text cell. Some of the text is italicized. The format for that particular cell is fine. However when the contents are included in the CONCAT, the formatting disappears.
It is possible to manually copy the result and paste values into another cell, and then format the relevant part of the text. However, I wondered if it were possible to carry over the formatting of the original cell as part of the CONCAT?
See attachment for what I mean. Thanks!

Hi - thanks for your speedy reply! I don't really want to bother with VBA; it's not much hassle to do the formatting manually. It would just have been more elegant automatically!
