Help needed, Spliting filenames into folders

I've found Leo's post
[Various simple rename presets)
Various simple rename presets
Which has presets to do almost all of what I need.

using 07 - Move to Artist Subdir.orp twice will sort author then location
I'd appreciate guidance on how to detect whether there are numbers in the middle section of the filename and if so to move the numbers from one side of the hyphen to the other.

Is it possible to string several presets together snd run them sequentially
Or am I going about this completely the wrong way?
