Remove numbers & dashes from title field

How can I remove numbers & dashes from multiple track at once, i know how to do them individually. In the TITLE field I want to remove them, multiple files at once
example
03 - song name
04 - song mane
05- song name

To get the TITLE
song name
from the TITLE
03 - song name

you can try it with an Action "Guess Values"
Source Format:
%TITLE%
and
Guessing pattern:
%dummy% - %TITLE%

For your example
05- song name
the guessing pattern is:
%dummy%- %TITLE%

I would use Format value or Convert>Tag-Tag for TITLE
Format string: $regexp(%title%,\d+\s*-\s*(.*),$1)
which should work for a number and any amount of spaces in front and behind the hyphen.
I hope we are not talking about the filename.
