Let's expand on this a bit, do you want to have customizable item names only be available with event prizes or something that you can have/purchase in general?

Ignore the "it's not possible because hurrdurr" posts, if there's demand in customizable item names we can update the shop to properly support it. I can see some fun ways with making items upgradeable and eventually having custom names for them but it needs some good system behind it. Just selling a possibility to customize 1 item for 100k might work well as a simple sink too but it'd only be available to rich players which is not an ideal way to go with it.
