Last day minus 3 days

[johnkors]

I have a job running on the last thursday of every month, "0 0 8 * * THUL". (which will occur in either the 3rd or 4th week of the month)

Is it possible to create an expression that provides the occurences 3 days before the occurences returned from the above expression? ("every monday of the week of the last thursday in month").
