Yeah. Mark, I'll hit on a couple of those. And then, maybe I'll turn it over to Kelly to talk about, customers as it relates to utilizing our VMS vendor-neutral program versus our MSP product. On the fill rate side, we did see fill rates across the industry at the beginning of this year that were lower than what it had historically been. And that's, of course, because of the really high demand that we saw at the peak of the pandemic. And then it got to a point back to where it was respectable, it was at the levels that we had experienced before the pandemic and that would have been kind of the March, April time frame. And then, right now what the entire industry is experiencing, just over the past couple of months on fill rates is, that they have declined a little bit. Which you would expect with the excessive demand that we have out there, right now, across the entire industry. Within our own MSP programs, as well as our vendor-neutral programs, we do rely heavily on our supplier partners. So they've been able to help quite a bit with those fill rates to help support our clients. Of course, we're very appreciative of those partners. As it relates to retention of our own health care professionals, of course, we've seen that kind of go up and down throughout the past year as well. If we kind of went back to, like, Q2, Q3 time frame of last year, we did see some declines in our retention rates, in skills such as like OR whenever electric procedures were paused and then it did return to some of the levels that we would experience historically. Q2 of this year actually did go down again on our retention, but that was more of a skill mismatch. So you had some of these COVID vaccine projects that were in place or replacing pharmacy techs, for example, and for the most part those COVID vaccine projects have gone away. And so there's no where to put those clinicians. Of course, we're only one month into the third quarter, but the retention rates of clinicians across both Nurse and Allied are back to where they were pre pandemic.
