This should already work right now. Most blocks can be aligned to the left or right. When choosing one of those options, paragraph text following it should flow next to it. It's possible you have a theme issue that needs addressing. Maybe try checking in with your theme author if this doesn't work for you.

Here's an example of aligning a cover block to the left with the text moving to the right. This is with the theme we use here at the Tavern.
