Help with Paneling Tools

I’ve been trying to flow a pattern on the following polysurface for a while now and I couldn’t get the pattern to look even and continuous where the edges of the two surfaces meet by only using flow along surfaces. I searched a lot and came across paneling tools but I’m very new to it. I’m not quite sure yet if its possible through paneling tools but I’m really clueless about any other commands or plugins that will do the job. Please guide me whether it really is possible through paneling tools and if yes, how to apply them in this particular case. Also if anyone knows any other command that might help, please let me know
