Configurable global default for refreshKey

Unless I specify refreshKey for a particular code, it defaults to 2 minutes for BQ and to 10 seconds for other databases. That is really wasteful in our case. We update analytics once a day, to hitting database after 10 seconds is not necessary, a refreshKey of 'every 1 hour' will be more useful. I can change it for each cube, but this is tedious and error-prone work.

I would like a way to specify default refreshKey in configuration. Either as constant, or maybe as function taking database kind/name/appId/whatever.

I considered manually editing all cubes, but this is fragile - I can miss a cube, or a colleague can add a cube in future without setting refreshKey
