how to fit text box to text automatically (like indesign)

is there a way to make text boxes fit to the text that lives inside?

i'm working on a comp & if i change the font size of text in a box, the text overflows the box & it makes alignment with other elements after the fact difficult (or impossible).

i did create the text boxes initially by clicking & typing - in other words i didn't drag a text box and then type.  i did see on these forums that if you don't drag a text box when it's created that it should automatically fit around the text, but if i change the font size after the fact, the text overflows.

anyone have any insight or workarounds for this?

it would be great to see an option to "fit frame to text" like indesign.

thanks!
