Creating an Split Field By Separator Action Item

Is it possible to crate an action item that splits tags that are separated by a semicolon followed by a space character? If so, how? We get weird results if we follow the normal procedure, which works well if there is only one character such as just the semicolon.

-d2b-

Then simply replace all semi-colon + space character sequences with a semi-colon beforehand.

Another proposal ...

Convert | Tag - Tag | ALT+5

Select format string

Field:
ARTIST

Format string:

$replace(%ARTIST%,'; ','\\\\')

Preview
From:
John Lewis; Mick Jagger; Ringo Harrison
To:
John Lewis\\Mick Jagger\\Ringo Harrison

... will give ....
ARTIST=John Lewis
ARTIST=Mick Jagger
ARTIST=Ringo Harrison
