Yeah. Thanks, Patrick. So, just also to be clear, we have not incorporated into guidance any revenue or costs impact of the expanded primary care sales force. As I noted, based on the way we've modeled this, we believe the incremental revenue delivered by that expanded sales team will more than offset the cost. So that would all be upside obviously on both the revenue and the earnings line. We're finalizing those plans and would expect to go into more detail on that, but we wanted to give at least a big picture vision of where this will progress over the next year or so. So just to step back, we have 170 representatives now, and we expect that we will ultimately need 320 representatives and that would cover the largest prescribing primary care physicians. And we'll detail that out in some additional calls in the future. We expect the first wave, we would add 65 of those 150 new additions, and that's the wave that we would expect to do in the second half of this fiscal year. Obviously, then that leaves the next wave or two for fiscal year '21. And so, that's how we're thinking about this expansion. And one of the reasons we won't do everybody at once is, we want to make sure that we do this right that anytime you hire that many sales people, you want to make sure they're effective hires and we want to ensure that's the case. We also want to take advantage of where we have coverage, so that we're doing so in a very appropriate cost conscious manner. So, for example, we know with UnitedHealthcare, we have the ability to look by ZIP code level at where we have higher levels of UnitedHealthcare coverage. And so, we actually have modeled for each ZIP code what the ASP impacts are, for example, of a United decision and a Medicare LCD expansion. And so, we will target territories based specifically on those modeled ASPs, and that's why we think that first wave is going to be somewhere around a 65 salesperson size. So, not only do we have the increase of reimbursement for GeneSight, but as you know Patrick, adding that many additional sales people actually has the opportunity to double the market potential just in a number of physicians that we're calling on. So I think we've got two opportunities here for some pretty substantial GeneSight expansion over the next couple of years.
