Simple Feature Request for Modders Regarding Signs/Banners

[Recatek]

Currently every building in the FCS has an "Is Sign" true/false flag that lets that building be placed on the walls of another building. Unfortunately, this "Is Sign" flag also makes the sign unselectable (so you can never dismantle it later). Would there be any way to separate out these two things ("Is Sign" and "Is Selectable") into two different flags in the FCS? Would make customizable faction banners for example way easier to mod in and manage if you can easily deconstruct them in-game.

Thanks!
