Can we have an option to stack RoA early like we can with Archangel?

Most of the time with mages, if you want to build , you have to do it as soon as possible since it only begins to "stack" when you have the full item. This is very limiting on a lot of mages since its stats and utility could be very usefull for a lot of them, but they can't afford to build it early enough when compaired to some other "necessary" items that their kit needs more. However, with , you can just build and then you can upgrade whenever you feel to, there's no immediate drawback to priotise other items over fully built Archangel.

So, I feel like we should have the option to add a new item to RoA's build path that could start stacking and share its stacks with the completed item, while having some kind of limit, like having a limit of 5 maximum stacks before upgrading. This way, a lot of mages could have more item building paterns while not necessarily becoming straight out op.
