Sales IQ needs to capture both first and last names

Sales IQ needs to capture both first and last names

Sales IQ chat only has one field for name. When this then syncs with Campaigns, the field populates the "last name" field in Campaigns. However most people fill in the "name" field of Sales IQ with either their full name or their Christian name.
This means that we then have to manually edit each person. Otherwise if we send out a campaign to "Mr" "Last name" then the email could be received as "Mr Bob" which looks like spam.
If there are 2 fields in Campaigns and Sales IQ syncs with Campaigns, then surely there should be 2 fields in Sales IQ?
