CloudStack 4.4 Adding additional IPs to Instance

We have been testing cloudstack in house for a brief time. So far it seems like a great platform but one thing I cant seem to figure out is how to add additional IPs to an instance. 

When I googled how to do it, it says there should be an IP address button on the NIC tab under instance, our particular install does not appear to have this. 

If you have any experience with CloudStack I would appreciate your help, thank you in advance. 

What version are you running?

(I read the title..)

Just to clarify in case the title is missed, we are running the newest version (as of this post) which is 4.4.x . 

I believe there's a bug report (+fix) for this already: https://issues.apache.org/jira/browse/CLOUDSTACK-7782

(replace ui/scripts/ui/widgets/detailView.js with https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;a=blob_plain;f=ui/scripts/ui/widgets/detailView.js;h=9c73911f3dcaecd8327f76c84043c115fdb184d9;hb=d9fcb87 )

Thank you for that, it worked to give me the option to add a secondary IP. 

The function itself leaves something to be desired but it does at least work.
