Unfortunately, no.
You could have rolled the before tax 401(k) money to the Traditional IRA and the after-tax money to a Roth. If it was all put into the Traditional IRA then it becomes part of the after-tax "basis" in that IRA and can never be removed by itself, but must be prorated between any distributed and the remaining total value of the IRA.
