Detailed Description: CROSS REFERENCE TO RELATED APPLICATIONS The present application claims the benefit of and priority, under 35 U.S.C. § 119(e), to U.S. Provisional Application Ser. No. 62/488,404, filed Apr. 21, 2017, entitled “Disposable Loading;” and 62/539,053, filed Jul. 31, 2017, entitled “Component Collection.” The entire disclosures of the applications listed above are hereby incorporated by reference, in their entirety, for all that they teach and for all purposes. FIELD The present disclosure is generally directed to separating components from multi-component fluids, in particular, toward apheresis methods and systems. BACKGROUND There are two common methods for blood donation/collection. The first is whole blood donation from a donor, followed by a centrifugal process that separates blood components from the whole blood based on the density of the blood component. The desired component can be manually, semi-automatically, or automatically moved to a collection container during, or possibly, after the whole blood is under the effect of the forces produced by the centrifuge. The other method may be an apheresis collection that requires a specialized machine. The apheresis method extracts whole blood from a donor while the donor is connected to the specialized machine. The whole blood can again be centrifuged to collect only the blood component (e.g., plasma) that is desired and can return all other blood components not desired back to the donor during the same donation. The donor is connected to the apheresis machine during the separation and collection of the blood component. Unfortunately, the apheresis process can be lengthy and uncomfortable. Often, the donor must remain connected to the machine for an hour to obtain a blood component donation. Thus, making the donation procedure more efficient is an ongoing desire for apheresis collection sites. SUMMARY There is a need for a plasma or other blood component system that can reduce the donation time and increase the comfort of the donor. Embodiments presented herein can increase the efficiency of the donation process by using the separated blood component to push or drive the non-desired blood components back to the donor without stopping and restarting the centrifuge. Thus, the embodiments herein make the donation process more efficient and faster for the donor. Embodiments may also provide methods and apparatuses for positioning portions, e.g., loops, of disposables in medical devices. Embodiments may involve use of surfaces for automatically guiding loops. In some embodiments, the medical devices may be blood separation machines, such as apheresis machines.
