Creating Paragraph Header Style With Wavy Line - GREP?

[#1]

Hi All, I have a paragraph header style. For each of these headers instead of having a line to each side of this header I wanted to have a wavy line. This wavy line would flank each side of the header title. Would I use a GREP style to make this happen. I want to make sure the space between the wavy line on each side and the header title is evenly spaced out. Could someone be kind enough to walk me through how to do this. Thanks.

No, not a GREP, use a distinct paragraph style and in the border section choose, what you want to have.
