Import IP address option under find unmanaged computers

Using find unmanged computer options saves lot of time because we need not have to create package for each group and save it in hard disk.
Since IPs are scattered, we cant get the list by using subnet range.
hostname takes just one entry, even if I want to install on 5 machines which are in different group, i need to create a package and save it in hard disk, then use clientremote.exe

Under Find unmanged computers there should be an option to import ip address list, the same what we get using clientremote.exe

I dont use clientremote.exe because for it, I need to create different packages and uses lot of disk space as we have thousands of group.
If we can have import ip option,i can put the list and from the drop down menu select the features and group. Will make installations lot easier.
Hope this gets implimented soon.
