Xencenter requires me to download the same update over and over

When using XenCenter 7.0.1.3852; and installing patches onto my Xenserver 6.0.2, and 6.5 servers, I have to download the patch each time I apply it to a server. I have not tested patching multiply machines in the same instance. This may be a feature, but having to download a patch 40 times for 40 servers, and I can only have one in MM at a time is rather annoying.
