Cell formatting rules global by project only

Currently the only options for creating cell formatting rules (by column or row) is to set up the rule manually for every single page/sub-page that needs the formatting, or to set the rule as a global one that will be applied to all pages in the studio's site.

However, our studio is using Shotgun for multiple projects, often with widely varying needs/pipelines. So it would be incredibly helpful to be able to set formatting rules as global within that project only. (I've looked around, and am fairly certain this is not currently an option...)
