Hello,
This is not possible. However, you could rename the com_hotproperty.php and .xml from extension installation package to the name you need and with a small change in the code, it should work. E.g. for com_winecountry:
Rename the files to com_winecountry.php and com_winecountry.xml. In com_winecountry.php change the class name from sefext_com_hotproperty to sefext_com_winecountry. In com_winecountry.xml change the line
<filename sef_ext="hotproperty">com_hotproperty.php</filename>
to
<filename sef_ext="winecountry">com_winecountry.php</filename>
Now you can pack the two files to ZIP again and use the JoomSEF's installer to install them the usual way.
Use the similar steps for other components. You can also buy our support time at
