Can IDT custom synthesize a dual-labeled oligonucleotide (5' FAM/3' TAMRA)?

IDT can synthesize dual-labeled probes on several scales with a variety of fluorophores and quenchers including 5' FAM and 3' TAMRA. Scales range from "mini" up through a custom large scale request. In addition, a second quencher (ZEN Quencher) can be added to decrease background and increase signal.
