Overwriting User Objects

Hello everyone!

I've been using user objects a lot (both to create complicate systems and to group together combinations of components that I use often)

but the problem is that (at least the way I use them) I cannot overwrite them If i've made a correction on them.

The way I use is this:

1) select a component I've just made

2) select "create user object", name it and I'm done.

if i make a change on it, I have to go to "special folders/user objects" erase the old one and repeat the previous steps.

is there some simpler way? 

thanks!
