Idea for Practice Tool (would appreciate feedback)

I think that being able to save your item build in the practice tool for use in actual games would be a nice feature. It would mostly just save time for everyone that makes specific item builds.

I understand that it would probably take a lot of effort on Riots part to implement something like this and that it might not even get used that often, but I thought it might be a nice feature to have and add more uses to the practice tool.

Would love to hear feedback on this like: wether you would use it or not, is there a benefit to having such a thing (from both user and developer sides), it even a good/plausible idea, etc.
