Question : How to modify a MS SQL Server 2005 table record for the value of a field that contains multiple values?

I am working with a table in SQL Server 2005.

I have a table named tableA and it has a field named SystemContact and a field named Application.
The field SystemContact can have multiple values for any record. The values are people's
names followed by a semi colon.
Let's assume that for a tableA record where Application = 'WLD',
SystemContact has a value as follows:
John Smith;Joe Franks;Jill Fieldstone;Bob Rowe;George Blanda

Is there a SQL Statement that could update the record where Application = 'WLD', so
that the SystemContact value will be changed to the following value:
John Smith;Joe Franks;William Stemp;Bob Rowe;George Blanda

In this record, the SystemContact value of Jill Fieldstone has been changed to William Stemp.
