How to override exemption certificate for one-time taxable purchase, the sequel

Continuing the discussion from How to override exemption certificate for one-time taxable purchase?

It seems that the old method of entering a pre-defined value into the Entity Use Code field in the sales order release screen no longer works as it previously did. I don’t know if this is simply due to CertCapture being discontinued and now a new method is required with Exemption Certificate Management. Has anyone needed to accomplish this since the sunsetting of CertCapture?
