Resharper Custom Pattern to convert string concatenation, in particular to an interpolation string

Question

I would like to replace all string concatenation instances in our custom logging with string interpolation. Now I know that ReSharper has rules for converting string concatenation to interpolation, but it only works if the text is selected. I want to apply a custom template for viewing, since the parameter is created exclusively by concatenating strings, and then changing it to interpolation.

Can someone help me create this custom template or let me know if there is a way to bring the templates together a bit
