Information about a rune

[Angel of Sonoma]

Does anyone have information about the rune in the screenshot below? All of my other runes simply say 'Recall Rune' in yellow text. This one says 'Shop Recall Rune'. I don't recall seeing any like this in the past.

If you mark a rune while standing inside a house, it becomes a shop recall rune. Shop recall runes automatically name themselves whatever the houses name is, and also cannot be remarked or sold to NPC vendors. They were created to prevent people from picking up other peoples runes at the bank to sell them or remark them, and also to make it so people don't have to type the name of their shop on every single rune.
