Proactive Outreach Tags

Can we please, please have the Proactive Outreach feature stop completely overwriting tags when you add them through the outreach tool? 

Right now, if I send Sally a proactive outreach and use that outreach upload to tag her contact with “Outreach 1” that tag will show up. But then, when I send Sally another outreach and use it to try to add tag “Outreach 2” the system removes “Outreach 1” and I lose that data. 

Especially since there’s no record of outbound emails, these tags are the only way that we are able to know that the outreach was sent and it’s really irritating to lose that information.
