RegExp in Rules

Not supporting expressions like (mp3|wav|avi) ?
I have:
File to exclude *.*\.(mp3|wav|avi)

when reload toucan, i see that:

File to exclude *.*\.(mp3
File to exclude wav
File to exclude avi)

seems toucan use | character in the Rules.ini to merge equal rule sections, and regexp alternation operation conflicts it.

maybe decision will be to double | character in the INI? as for \ character
