pushing the upper text line to the right with bottom text

I’m using indesign cc and I’m making a magazine layout. I have a review section with around 20 pages (music) where at the bottom of each review there is a rating and the name of the journalist.
I would like to push the upper line for the right with some bottom line text. Here goes an example:

Example of text, example
of text example of text
8 By Nuno Santos

I would like that when increasing the size of the 8 character, the upper line moves giving space for number 8.
By increasing the size of number 8, it will occupy both lines

Example of text, example
-> of text example of text
8 By Nuno Santos

Is this possible without creating an independent text area?

At the moment when increasing the size of number 8, it only overlaps the text above. It doesn’t pushes it to the right
