I'm trying to create a new view for one of our SDRs. We have active calling and email campaigns for our SDRs, however they are not the lead owners so their 'hot' leads aren't showing up in their feeds. I'm trying to create a new view that will show the SDR's hot leads, but can't figure out what additional filter I could use. The only thing that I can think to use is "activity is logged" or "sales email sent" and those aren't available filters. Does anyone have any experience with this?
