ELA and DHCP with workstation logs

ELA and DHCP with workstation logs

Does anyone else have an issue with the way ELA stores both the DNS name and the IP address to identify a workstation?   I have an issue in which when a new computer gets a previous IP address that was used with a registered computer, I can not add the workstation because it states the computer already exists.   There are situation that once a workstation is registered, it might receive a new IP address later (nature of dhcp), I am unable to add a new computer because it received the previous IP address.  I submitted a ticket on this but support told me it is working as designed.  I have a hard time believing no one else is experiencing this issue.  

ELA works fine for my servers as they usually get a static address and their IP address never change but workstation are proving to very difficult to manage.  And you cannot delete the workstation host to re-add them with their new IP address from ELA as it will delete all logs and archive files.  

Am I alone in this frustration?
